If this were a starship combat game, rather than a space fantasy roleplaying game, we would make this section much more complicated. A ship's mass would make Piloting rolls more difficult, different weapons would be more or less effective against different defenses, and so on. But this is not a starship combat game, so this section is as simple as we could make it.

===Parts Of A Starship===
===Parts Of A Starship===
====Bridge====
The bridge is where the pilot controls the starship's movement. It typically has stations for the captain of the starship and a number of staff officers. On medium-size warships, the bridge may also include combat information center functions; on larger warships, the combat information center is a separate location.
====Engine Room====
The engine room provides more precise control of the power core and the warp engines, and may allow direct observation of them (behind appropriate safety shielding, of course). Larger starships may have several engine rooms, and the largest starships might have dozens.
====Fabricators====
Most starships of Class 3 or higher have fabricators. The fabricators on smaller starships are adequate for day to day needs, such as meals and simple shipboard items. Larger starships may have specialized fabricators for the med bay, a more complete meal library, and engineering fabricators for most replacement parts. The largest starships have a complete suite of industrial fabricators, and are capable of creating parts to build entire starships. If a starship also has an Exotic Particle Synthesizer Console, it can even construct power cores and warp engines.
====Grav Plates====
The perception of gravity on starships is provided by grav plates. Grav plates operate on the same electrogravitic principles as the thrusters used when a starship is near a planetary surface. Grav plates are mechanically simple and generally quite reliable: if a starship's grav plates have failed, something has gone terribly wrong.
====Hangar====
Starships of Class 4 or higher typically have a hanger. This hangar can accommodate either a single starship two Classes smaller (typically a ''squadron'' -- see [[ZeroSpace_4e_EN:Starships#Squadrons|Squadrons]], below).
====Hold====
All starships have at least one hold. The dimensions of the hold may vary considerably, from the size of a lunchbox to that of a small moon. The hold might have gravity plating and a breathable atmosphere, depending on its intended use, but it is not designed for habitation.
====Med Bay====
Every starship has a medical facility, although the size and sophistication of the facility varies a great deal. On smaller starships, a medical pod or "autodoc" can heal most injuries, or keep the patient alive until more advanced treatment may be found. Larger starships may have multiple, specialized medical pods, along with more advanced diagnostic and treatment equipment. The largest starships have full hospital facilities, although it is still called the "med bay".
====Passageways====
On Restoration Era starships, passageways are usually considered wasted space, and are made no larger than necessary: rarely wider than three meters.
On Panglossian Era starships, particularly Old Commonwealth starships, passageways were much larger. Class 3 Old Commonwealth starships had passageways two meters wide, while Class 5 and larger starships had passageways at least six meters wide and four meters tall.
Starships also have smaller access corridors used for maintenance. Such corridors are typically just wide enough to crawl through on Restoration Era starships, but are large enough for two engineers to work comfortably on Panglossian Era starships.


====Power Core====
====Power Core====


Starships generally use hybrid fusion-singularity reactors. The fusion furnace, the singularity containment system, and all associated components are referred to as the ship's "power core".
Starships generally use hybrid fusion-singularity reactors. The fusion furnace, the singularity containment system, and all associated components are referred to as the starship's "power core".


Power cores are "fired up" or "brought online" to make them ready for use, and "shut down" or "taken offline" to render them inert. Bringing a power core online typically takes 6 hours, or 2 hours if the power core has been in use within the last 24 hours. Taking a power core offline takes less than a second, but there are numerous safety checks which follow, taking around an hour.

Taking a power core offline takes less than a second, but there are numerous safety checks which follow, taking around an hour.
====Screens====
"Screen" is a catch-all term for the ubiquitous audiovisual displays aboard a starship. Holograms can be "brought up" or "shut down" with a gesture, or higher-resolution images can be displayed on physical monitors. The display is often augmented to provide additional data: sounds may be added to represent the activity of an object on the screen, such as the firing of weapons or the explosion of an engine; weapons such as particle beams, which are invisible to the naked eye, are spectrum-shifted to be visible; and so on.
====Sensors====
XXX
short range is weapons range
medium range is sensor range
long range is beyond most sensor's range
====Thrusters====
A starship's conventional engines, used for moving the starship through relatively normal space, are referred to as "thrusters". Electrogravitic thrusters are typically used when within a kilometer of a planetary surface or other inhabited area, with fusion thrusters engaged once the starship leaves this safety region. A typical starship can lift off from a planet and clear the atmosphere in a few minutes.


====Warp Engine====
====Warp Engine====


Warp engines create a microscopically-thin Lorentzian manifold of spacetime around a starship -- typically called a "warp bubble". This allows the ship to remain relatively motionless while also achieving velocities which are relatively relativistic.

Warp engines are "fired up" or "brought online" to make them ready for use, and "shut down" or "taken offline" to render them inert. Bringing a ship's warp engines online typically takes 3 hours, or 1 hour if the warp engines have been in use within the last 24 hours. Taking the warp engines offline takes less than a second, but there are numerous safety checks which follow, taking around an hour.

Taking the warp engines offline takes less than a second, but there are numerous safety checks which follow, taking around an hour.


Once online, warp engines are "engaged" to activate the Lorentzian manifold generator and move the ship toward the set destination, or "disengaged" to return the ship to relatively normal space. The warp engines are typically disengaged at a pre-set arrival time, which nearly always puts the ship where the navigator expected. However, the warp engines may be disengaged manually, placing the ship into relatively normal space somewhere between the ship's origin and its destination.
Before the warp engines are engaged, a destination is selected and the anticipated arrival time is calculated. Engaging the warp engines activates the Lorentzian manifold generator and moves the starship toward the pre-set destination. The warp engines are typically disengaged at a pre-set arrival time, which nearly always puts the starship where the navigator expected. However, the warp engines may be disengaged manually, placing the starship into relatively normal space somewhere between the starship's origin and its pre-set destination.


While the warp engines are engaged, the ship is unable to communicate or interact with the universe outside of the warp bubble.
While the warp engines are engaged, the starship is unable to communicate with or interact with the universe outside of the warp bubble.


===Starship Character Sheets===
====Windows====


Starships have a Class, four base attributes, and four secondary attributes.
What a crew member sees in a window may be augmented with distinct sounds or overlaid visuals, such as a target's range or mineral composition. Sophistication of the display and any audio accompaniment varies by starship and manufacturer. Some starships have a "privacy" mode, which looks the same from the inside, but looks like a glowing white haze from the outside. And of course, a starship's windows automatically compensate for the luminosity of what is outside the window.


The core trait of a starship is its Class, which is a number from 1 (the smallest ships) to 10 (the largest ships). A ship's Class determines the starting value of its attributes, the number of consoles it may equip, the size of its crew, and so on.
===Starship Attributes===


A starship's base attributes are Consoles, Engines, Hull, Shields, and Weapons. The starting value for each of these attributes is equal to the ship's Class. A ship's secondary attributes are Armor and Evasion. The starting value for each of these attributes is given in the table below.
As with characters, a starship's attributes are ranked from 1 (the smallest starships) to 10 (the largest starships), and can't be reduced below zero or above 10. A starship has one core attribute, its Class, and five secondary attributes, its Consoles, Engines, Hull, Shields, and Weapons. A starship's Class determines the starting value of its other attributes, the size of its crew, and so on.

Each attribute can be modified in a number of ways, from a minimum of 0 to a maximum of 10. Here are some examples of modifying the rating of a starship's Consoles (there will be a full list further down):
 
*The Experimental subclass (X) increases Consoles by 1.
*The Escort starship type reduces Consoles by 1.
*A Bha'atar-manufactured starship reduces Consoles by 1.
*A Zniss-manufactured starship increases Consoles by 1.
 
====Consoles====
 
Consoles are a form of starship equipment. As with personal equipment, a console's equipment bonus replaces or adds to a player's skill roll (see [[ZeroSpace_4e_EN:Skills|Skills]].
 
Some consoles provide additional capabilities to the starship (see [[ZeroSpace_4e_EN:Starships#Starship_Consoles|Starship Consoles]], below).
 
====Engines====
 
The Engines attribute reflects the capacity of a starship's power core and the maximum strength of its electrogravitic thrusters, fusion thrusters, and warp engines.
 
====Hull====
 
The hull of a starship is one of its toughest parts. Only portions of the power core are more durable. A starship which is large or densely constructed will have a higher Hull than one which is smaller or less dense.
 
====Shields====
 
Energy shields on a starship serve two purposes. The primary reason for shields is to protect the starship from hazards such as micrometeorites, ambient high-energy particles, and other interstellar debris while traveling in realspace. No roll is required for this, as it's an automated and highly redundant function, much like life support.
 
The secondary purpose of shields is to protect the starship against hazards such as exploding stars and attacks from other starships. The rating of the Shields is subtracted from the points of damage dealt by a successful attack.
 
Energy shields lose effectiveness as they withstand attacks. A starship's shields grant their full protection value against the first successful attack in a scene. The second attack against a starship in a scene, the shields grant one less than their full protection value. This continues until the protection value granted by the shields is reduced to zero (the shields "go down", in common parlance). The shields will be restored to full effectiveness after the fight is over, when the shield coils have had a chance to recharge.
 
The starship's engineering team may also attempt to restore the shields during combat (see [[ZeroSpace_4e_EN:Starships#Repairing_The_Ship|Repairing The Starship]], below).
 
====Weapons====
 
The number of attacks a starship may make per round is equal to its Weapons. The starship may be able to make additional attacks provided by its consoles, but those are handled separately (see [ZeroSpace_4e_EN:Starships#Starship_Consoles|Starship Consoles]], below).
 
Note that the starship's Weapons attribute is not the physical number of its weapons. A starship with Weapons 5 might have only two physically distinct weapons, or it might have twenty, depending on the design, size, and placement of the weapons themselves. A starship's weapons may be described however the GM likes, but this is merely flavour, and makes no actual difference in combat. Here are some examples, but you are not restricted to these options.

Each attribute can be modified in a number of ways. Here are some examples (there will be a full list further down):
====Armor====


*The Escort subclass (E) reduces Consoles by 1.
Armor reduces the points of damage the starship takes from a successful attack. The starting value for a starship's Armor is one-half its Hull rating (round down, even if the fraction is more than one-half, to a minimum of 1). The starship's Armor is subtracted from the points of damage dealt by a successful attack.
*The Experimental subclass (X) increases Consoles by 1.
*A Bha'atar-manufactured ship reduces Consoles by 1.
*A Zniss-manufactured ship increases Consoles by 1.

The categorization and nomenclature of starships is a field rife with inconsistency. The Old Commonwealth had hundreds of starship classes, and the New Commonwealth is on its way to matching that achievement. In contrast, the Bha'atar have only two main classes of starship: warships ("starhawks", in Bha'atar parlance) and support ships ("rousters", in Bha'atar parlance).

This is not a system of nomenclature that lends itself easily to direct comparisons, so the game system will refer to the ship classifications below. Any resemblance between this system and that used by any interstellar fleet is purely coincidental.

===Subclass E: Escorts===
Escort ships (indicated with an "E" after its class) are less flexible than multi-purpose ships like cruisers, allowing an escort to have a smaller silhouette and a commensurately smaller crew. There is a cost, however: the maximum number of consoles an escort ship may have is one less than its class would indicate. For example, a class 6 escort could have five consoles installed.


===Subclass X: Experimental===
===Subclass X: Experimental===


An experimental ship (indicated with an "X" after its class) may have one more console than its class would indicate. For example, a class 3X corvette could have four consoles installed.

===Ship Class And Crew===
===Starship Class And Crew===


On very small ships, a single crew member may be responsible for some or all of the ship's systems. In a fighter, for example, the pilot, the navigator, and the engineer could all be the same person. On larger ships, these responsibilities are usually distributed among specialists: the ship may have several pilots, navigators, and engineers, as well as dedicated scientists, sensor operators, and medical professionals.

"Minimum crew" refers to the absolute minimum number of crew required to operate a Restoration Era ship at full effectiveness for one shift. "Full crew" can vary considerably. The number of full crew given above is for a New Commonwealth (Restoration Era) starship, where the crew complement is generally three and a half times the minimum crew: sufficient for three shifts and an occasional off-duty day for each crew member. Bha'atar ships have the same number of minimum crew, but operate two shifts continuously without any off-duty days. A typical Bha'atar destroyer has 96 crew members (double the minimum crew for a destroyer). However, Bha'atar tours of duty are typically shorter than those in the New Commonwealth.

====Old Commonwealth Crew Sizes====
====Old Commonwealth Crew Sizes====


Old Commonwealth (Panglossian Era) ships could operate with less than one-quarter the crew of a comparable New Commonwealth ship, thanks to extensive automation and the ship's AI, or "geist". Old Commonwealth ships class 4 and larger normally carried six times the minimum amount of crew; Old Commonwealth crews worked fewer, shorter shifts than New Commonwealth crews are expected to work. A typical Old Commonwealth heavy cruiser had a minimum crew of 24 and a full crew complement of 144, compared to 96 and 336 for a New Commonwealth heavy cruiser. Despite the smaller crews, Old Commonwealth ships were as large if not larger than equivalent New Commonwealth ships, and their interiors were cavernous by comparison.

===Initiating Conflict===
===Initiating Conflict===


As with [[ZeroSpace_4e_EN:Actions#Initiating_Conflict|normal combat]], conflict begins when one side decides to stop talking and start shooting. If a character wishes to initiate a conflict, the captain of each ship makes a Survival (Presence) roll. If one or more ships get the drop on their opponents (an ambush, for example), the captain of a ship with a situational advantage gets a +{{KM4_SKILL_BONUS}} skill bonus to their Survival (Presence) roll. Actions proceed each round from the crew whose captain rolled highest to the crew whose captain rolled lowest, with the characters on each ship taking their turns in whatever order they would like. A ship, like any piloted vehicle, moves when its pilot takes their turn. When every character has had the opportunity to take a turn, the ship with highest initiative goes again, and so on until the conflict has ended.

While the player characters are handling the important tasks, the ship's other crew (if there are any) are firing weapons, performing scans, dealing with the wounded, and making repairs, but it all goes more or less as planned and has no impact on the outcome of the conflict.

'''2d6 + [attribute] + [skill bonus or equipment bonus]'''
'''2d6 + [attribute] + [skill bonus ''or'' equipment bonus]'''
 
In game terms, starships operate much like characters' personal equipment. Each crew member may use a standard action to make a skill roll, as usual. The player rolls their dice, counts the dots, adds the character's relevant attribute, and adds their skill bonus or their equipment bonus. If a character has an appropriate skill ''and'' the appropriate equipment, use whichever bonus is larger, and add +1.
 
There are three main tasks a crew member can undertake during starship combat: piloting the starship, firing the weapons, and repairing the starship.

Squadrons are a special case. Rather than a single starship, a squadron is an arbitrary number of small starships. If a squadron is controlled by the player characters, the characters may assume the roles of pilot, gunner, or engineer however they like, and their rolls affect the squadron as a whole. The squadron loses ships as it takes damage, but it's assumed the player characters are in craft that survive the battle.

'''Flee Pursuit:'' Fleeing pursuit is treated as an [[ZeroSpace_4e_EN:Actions#Extended_Task|extended task]]. If one pilot wants to leave the conflict but the other pilot doesn't, the fleeing pilot uses a standard action on their turn to attempt an Agility + Piloting roll vs. 8 + the pursuing pilot's Agility + Piloting. If the fleeing pilot achieves three successes and their ship has at least 1 Hull point remaining, the fleeing pilot eludes the pursuing pilot, and their ship leaves the conflict.

'''Avoid Obstacles:'' If the pilot succeeds at this roll, their starship is safe from collisions with unguided objects until the beginning of the pilot's next turn.
 
'''Set Destination:'' The difficulty of this roll is typically 12, or 15 if the starship is engaged in combat. If the pilot succeeds at this roll, they set their starship's course and engage the warp engines, secure in the knowledge that everything will go as planned and the engines will disengage at the proper time, returning the starship to relatively normal space near the intended destination. If something goes wrong, there is an alarm, but navigation errors are rarely fatal.


====Firing The Weapons====
====Firing The Weapons====


The number of attacks a starship may make per round is equal to its Weapons rating. The ship may be able to make additional attacks provided by its consoles, but those are handled separately (see [ZeroSpace_4e_EN:Starships#Consoles|Consoles]], below).

==Consoles==
 
Consoles are a form of starship equipment. As with personal equipment, a starship console's bonus replaces or adds to a player's skill roll.
 
'''2d6 + [Attribute] + [Skill ''or'' appropriate equipment]'''
 
If a character has the needed skill ''and'' the appropriate equipment, use whichever bonus is larger, and add +1.
 
 
===Panglossian Era Consoles===
 
Panglossian Era ships had two additional consoles, both at the same quality as the ship's class, up to mark V (for example, on a class 3 ship, these two consoles would be mark III; on a class 7 ship, these two consoles would be mark V). First, each Panglossian Era ship had a Geist Management Console permitting the ship's AI, or "geist" (a crew position), to manage the ship's myriad automated systems (this console was not removable, although it could be upgraded). Panglossian Era ships also had a Wormhole Network Interface Console , which granted the ship the ability to use the wormhole network. These consoles were in addition to the consoles a ship would be permitted due to its class. For example, a class 3X Panglossian Era corvette could have six consoles installed: these two, three more due to its class, and an additional console due to the "class X" rating.
 
==Other Equipment==
 
===Emergency Self Destruct===
 
Self destruct systems are present aboard most commercial and military starships. Initiating the self destruct on a spacecraft disengages its engine coolant system, quickly causing the vessel's power core to overload and explode, destroying the spacecraft after a set time period has elapsed (usually 10 minutes).
 
As a safety precaution, self destruct mechanisms are intentionally difficult to enable, and even more difficult to disable. Enabling the self destruct device requires an Agility + Engineering roll vs. 12. A self destruct device can be disabled during the first half of its countdown with a successful Agility + Engineering roll vs. 15.
 
A ship which self destructs will explode with tremendous force, utterly destroying the ship and severely damaging any nearby ships. Any vessel within short range of the exploding starship will take points of Hull damage equal to the Engines of the exploding ship, bypassing the target's defenses.
 
{{WIP}}
 
==Stop here, the stuff below is from the previous version==
 
Starships have attributes, which serve roughly the same purpose as a character's attributes. Starships have Consoles, Engines, Hull, Shields, and Weapons. A starship's attributes are used for its skill rolls, instead of using a character's attributes. If one of the players has a relevant skill, the player rolls 2d6, adds the starship's attribute, and adds their skill.
 
Some starships have specialized equipment such as camouflage fields, fully equipped medical bays, or tractor beams. These have their own special rules, given in the equipment's description.
 
===The Crew===
 
On very small ships, a single crew member may be responsible for some or all of the ship's systems. In a starfighter, for example, the pilot, the navigator, and the engineer are all the same person. On larger ships, these responsibilities are usually distributed among specialists: the ship may have several pilots, navigators, and engineers, as well as dedicated scientists, sensor operators, and medical professionals.
 
In game terms, starships operate much like characters' personal equipment: the player rolls their dice, counts the dots, and adds the result to the ship's attribute and the character's relevant skill. For example, a character piloting a starship would attempt a Piloting roll by rolling two dice, adding the ship's Engines attribute, and adding their own Piloting skill.


To make an attack with one of the starship's weapons, a crew member must use a standard action to attempt an Agility + Ranged Combat roll.

===Order Of Play===
As with personal combat, everything that happens in a round of starship combat is assumed to occur more or less simultaneously, but we make people take turns to keep the game orderly.
The most important factor in determining which starship acts before which is situational awareness. If a starship is not aware of their opponent, then they don't have the opportunity to attack. If the combatants become aware of their adversaries in a set order, then that is the order in which they act in combat.
However, if the various combatants become aware of each other more or less simultaneously, or if you would prefer to roll dice to see who goes first, the players and the GM should each make a Science (Reason + ship's Computer) roll at the beginning of the conflict. Turns proceed each round from the highest roller to lowest.
===Combining Effort===
Starship combat, piloting, and repair are exceptions to the [[ZeroSpace_4e_EN:Actions#Combining_Effort|Combining Effort]] rules. Combining Effort does not provide any additional benefit: larger starships have more to repair, but they also have larger crews, so it's assumed that everyone who can help with a given task already is, and it all balances out.
==Computer==
A starship's Computer is its most important asset, because without it, nothing on the ship works. The ship's computer can used to analyze data or to chart a course through space.


===Navigation===
If the attacker's Action Value meets or exceeds the target pilot's Defense Value, the attack succeeds.


Navigation pertains to getting from one stellar body to another. Navigation generally requires a Piloting (Reason + ship's Computer attribute) roll. The difficulty (DV) of the roll is based on how well-known the destination is.
====Hull Damage====


If the attacker's roll succeeds, the player rolls 1d6 and adds the Weapons rating of their starship. The target starship's Shields and Armor are deducted from this amount, and the remaining points of damage are subtracted the target's starship's Hull.

|}
|}




Note that the distance to the destination does not directly impact the difficulty. However, the more remote the destination, the farther off-course the ship will be if the navigator fails to chart the correct course.
When a starship takes points of damage, the points are temporarily subtracted from its Hull. A starship which has been reduced to zero Hull is disabled: it is out of the fight, and it will probably require extensive repairs. Hull may not be reduced below zero.


===Orbital Mechanics===
Starship weaponry is much more powerful than the weapons mounted on vehicles or carried by individuals. If a starship weapon is brought to bear against a vehicle, the damage roll is increased by 3. If a starship weapon is brought to bear against an individual, the damage roll is increased by 6. Conversely, if a vehicle weapon is brought to bear against a starship, the damage roll is decreased by 3 (minimum 0). If an individual weapon is brought to bear against a starship, the damage roll is decreased by 6 (minimum 0).


Orbital mechanics pertains to getting around within a solar system. Orbital mechanics usually requires an opposed Piloting (Reason + ship's Computer) roll. The typical reason for making an orbital mechanics roll is to reach a destination before someone else does, because it's not really possible to get lost within a solar system. The navigator who rolls higher has plotted a trajectory that will allow their ship to reach its destination several hours ahead of the other ship.
====Repairing The Starship====


===Sensors===
Normally, the crew of a damaged starship may repair half of the starship's lost Hull (rounded down, minimum 1) by working on it for about a day. Barring some extraordinary event, a starship's Hull will be completely repaired after a week in a stardock.


A starship's sensors are used to find things and to analyze them. Using a ship's sensors generally requires a Computing (Reason + ship's Computer) roll. The difficulty (DV) of the roll is based on the subtlety of the thing being searched for or analyzed.
=====Engineering Maneuvers=====


At the beginning of their turn, the chief engineer may declare that they are using one of the following maneuvers. Choosing a maneuver is optional, and does not require an action or a roll.


{| cellpadding="4" cellspacing="1" class="wikitable zebra"
'''Auxiliary Power To Engines:''' If the chief engineer declares "Auxiliary Power To Engines", the starship gains a +1 bonus to its Engines (maximum of 10), but it incurs a -1 penalty on its Shields and Weapons (minimum of 1). These bonuses and penalties last until the beginning of the chief engineer's next turn.
|+Table: Sensor operation difficulty examples
 
|-
'''Auxiliary Power To Shields:''' If the chief engineer declares "Auxiliary Power To Shields", the starship gains a +1 bonus to its Shields (maximum of 10), but it incurs a -1 penalty on its Engines and Weapons (minimum of 1). These bonuses and penalties last until the beginning of the chief engineer's next turn.

==Engines==
'''Auxiliary Power To Weapons:''' If the chief engineer declares "Auxiliary Power To Weapons", the starship gains a +1 bonus to its Weapons (maximum of 10), but it incurs a -1 penalty on its Engines and Shields (minimum of 1). These bonuses and penalties last until the beginning of the chief engineer's next turn.


A starship's Engines are its most important asset, because without them, it's going nowhere. Piloting a starship generally requires an Agility + Piloting roll. The difficulty (DV) is based on the complexity of the maneuver being attempted.
=====Engineering Tasks=====


Each round, each engineer on a starship may attempt a Reason + Engineering roll to repair the starship and restore disabled systems.

|}


'''Jury Rig:''' To restore a single lost point of damage during combat, an engineer must use a standard action to attempt a Reason + Engineering roll against 8 + Hull + points of damage their starship has taken. For example, if the starship normally has Hull 3, and has taken 2 points of damage, the DV of the roll is 8 + 3 + 2 = 13. If the engineer's roll is successful, one point of Hull is restored to the starship. However, the starship should visit a starbase for proper repairs as soon as possible.


A failed Piloting roll will usually result in damage to the ship. For every failed Piloting roll, the ship loses one point of Hull. It's difficult to destroy a starship by flying it poorly, but an exceptionally bad pilot can do it.
'''Restore Shields:''' To restore a single lost point of Shields during combat, an engineer must use a standard action to attempt a Reason + Engineering roll against 8 + Shields + lost Shields of their starship. For example, if the starship normally has Shields 3, and has lost 2 points of Shields from successful attacks, the DV of the roll is 8 + 3 + 2 = 13. If the engineer's roll is successful, one point of Shields is restored to the starship.


===Interstellar Travel===
'''Break Free:''' To break the starship out of an attack with an ongoing effect, such as a Tractor Beam Console, an engineer must use a standard action to attempt a Reason + Engineering roll against 8 + Class + Console Mk of the attacker. If the engineer's roll is successful, the starship breaks free from the ongoing effect.


<blockquote>
==Starship Consoles==
====SIDEBAR: Exact travel times====
 
There is no equation to give you exact travel times based on the distance traveled and the Engines and Hull of the ship. The GM should decide the travel time on a case by case basis, using the rough guidelines given here. The plot is always more important than an equation in some book.
</blockquote>
 
 
The time required to travel interstellar distances increases logarithmically as the distance itself increases linearly. For example, a journey between two star systems in the same region of a galaxy typically takes from a few hours to a few days, traveling from one edge of a galaxy to the other takes a week or two, and traveling from one galaxy to the next takes a month or two. Ships which have higher Hull ratings are slower than less massive ships, and ships with higher Engines ratings are faster than ships with lower Engines ratings. Travel using warp engines does not remove a vessel from our universe. However, due to the Lorentzian manifold (or "warp bubble") around it, the vessel is effectively blind, deaf, and incommunicado for the duration of its journey.
 
==Defenses==
 
===Evasive Maneuvers===
 
At the beginning of the ship's turn, the pilot may choose to initiate evasive maneuvers. Performing evasive maneuvers grants the defending ship a +{{KM4_SKILL_BONUS}} bonus on all defensive rolls. A ship which is using its action to perform evasive maneuvers continues to receive this benefit until the beginning of the ship's next turn.
 
A ship taking evasive maneuvers is not able to attack (the ship can fire its weapons, of course, but they won't hit anything).
 
===Shields Maximum===
 
At the beginning of the ship's turn, the crew members on the weapons and defensive consoles may agree to set shields to maximum. Setting shields to maximum grants the defending ship a +{{KM4_SKILL_BONUS}} bonus on all defensive rolls, but a -{{KM4_SKILL_BONUS}} penalty on all offensive rolls. Setting shields to maximum is a quick action. A ship which has set its shields to maximum continues to receive this benefit until the beginning of the ship's next turn.
 
==Hull==
 
A starship's Hull is its most important asset, because Hull reflects the physical structure and durability of the ship. A starship which is large or densely constructed will have a higher Hull than one which is smaller or less dense.
 
When a ship is successfully attacked, one is temporarily subtracted from its Hull. A ship which has been reduced to zero Hull is disabled: it is out of the fight, and it will probably require extensive repairs. Hull may not be reduced below zero.
 
Normally, the crew of a damaged starship may repair half of the ship's lost Hull (rounded up) by working on it for about a day. Further damage may only be repaired at a starship repair facility called a stardock. Most full-service starports have stardock facilities. Barring some extraordinary event, a ship's Hull will be completely repaired after a week in a stardock.
 
If the ship has taken some other form of damage, such as damage to one of its systems, this damage is temporary. It is all repaired once the crew has had a day to work on it.
 
==Weapons==
 
A starship's Weapons are its most important asset, because a starship without weapons is simply a moving target. Starships can attack a number of times per round equal to the ship's Weapons, or equal to the number of crew members at the weapons consoles, whichever is less (each crew member can fire the ship's weapons once, once per round). Using a ship's weapons generally requires a Warfare (Reason + ship's Weapons) roll against the defending pilot's Warfare (Reason + ship's Defenses) roll.
 
The ship's Weapons also dictates the range of its weapons. The range of the ship's weapons are covered in [[ZeroSpace_4e_EN:Starships#Range_Bands|Range Bands]], below.
 
Note that the ship's Weapons rating is not the number of its physical weapons. A ship with a Weapons rating of 5 might have only two weapons, or it might have twenty, depending on the design, size, and placement of the weapons themselves.
 
Starship weaponry is much more powerful than the blasters carried by individuals. If a starship weapon is brought to bear against an individual rather than against a structure or another craft, the damage roll is increased by 6.
 
===Range Bands===
 
As with terrestrial combat, there are five range bands in starship combat: close, short, medium, long, and extreme. Standard starship weapons have an effective range based on the Weapons rating of the ship. Due to the vast distances involved, attacking more distant targets is usually not possible.
 
The "typical weapons" listed below are mostly for flavour. They don't usually make any difference in the game.
 
 
{| cellpadding="4" cellspacing="1" class="wikitable zebra"
|+Table: Starship range bands
|-
! class="aligncenter" |Weapons
! class="alignleft" |Range
|-
| class="aligncenter" |1-2
| class="alignleft" |Close (1 km)
|-
| class="aligncenter" |3-5
| class="alignleft" |Short (10 km)
|-
| class="aligncenter" |6-8

|-
| class="aligncenter" |9-11
| class="alignleft" |Long (1,000 km)
|-
| class="aligncenter" |12+
| class="alignleft" |Remote
|}
 
 
If you'd prefer to emulate a setting more like ''Star Trek'' and less like ''Star Wars'', multiply the weapon ranges by one thousand. So instead of close, short, medium and long ranges being 1 km, 10 km, 100 km, and 1,000 km, they'd be 1,000 km, 10,000 km, 100,000 km, and 1,000,000 km. (This doesn't actually make any difference in the game.)
 
===Targeting Specific Systems===


Consoles are a form of starship equipment. As with personal equipment, a starship console's bonus replaces or adds to a player's skill roll.


===Panglossian Era Consoles===


Before resolving whether an attack is successful, an attacker can declare that they are targeting a specific system: bridge, cargo, computer, crew quarters, defenses, engines, engineering, gravity control, environmental systems, sensors, or weapons. If the attack is successful, the attacker then rolls 2d6 and consults the "Targeting starship systems" table. If the attacker's system targeting roll is within 0-2 of the desired system, that system is affected as described; otherwise, the system rolled is affected as described.
Panglossian Era starships had two additional consoles, both at the same quality as the starship's Class, up to mark V (for example, on a Class 3 starship, these two consoles would be mark III; on a Class 7 starship, these two consoles would be mark V). First, each Panglossian Era starship had a Geist Management Console permitting the starship's AI, or "geist" (a crew position), to manage the starship's myriad automated systems (this console was not removable, although it could be upgraded). Panglossian Era starships also had a Wormhole Network Interface Console , which granted the starship the ability to use the wormhole network. These consoles were in addition to the consoles a starship would be permitted due to its Class. For example, a Class 3X Panglossian Era corvette could have six consoles installed: these two, three more due to its Class, and an additional console due to the "Class X" rating.


For example, if the attacker was targeting the bridge (requiring a roll of 2), and the attack was successful, and rolled a 4, they would have successfully damaged the bridge. If they rolled a 5, however, they would have damaged the starship's computer, reducing the ship's Computer rating to zero until the end of the attacker's next turn.
===Restoration Era Consoles===


Targeting a specific system damages a system instead of causing damage to the ship's structure; the target's Hull is unchanged.
====Tractor Beams====


Tractor beams are gravitic weapons intended to prevent the target from moving.


{| cellpadding="4" cellspacing="1" class="wikitable zebra"
Tractor beams do not deal points of damage to the target. Instead, on a successful roll, the Engines rating of each starship is subtracted from the Engines rating of the other starship for as long as the tractor beam is focused on the target. If either ship's effective Engines rating is reduced to zero, the starship is unable to move.

===Camouflage Fields===
===Emergency Self Destruct===


Camouflage fields are an unusual defensive system based on the theory that an opponent can't destroy what they can't target. Camouflage fields do not provide any protection against damage. Instead, an attacker must make a successful Science (Reason + Computer rating) roll each round before they can attack a ship with an active camouflage field, in a high-tech version of "hide and seek".
Self destruct systems are present aboard most commercial and military starships. Initiating the self destruct on a spacecraft disengages its engine coolant system, quickly causing the vessel's power core to overload and explode, destroying the spacecraft after a set time period has elapsed (usually 10 minutes).


If the Computing (Reason + Computer rating) roll of the sensor operator equals or exceeds the Science (Reason + Computer rating) roll of the camouflage field operator, the seeking ship may attack the hiding ship during its turn; if not, then not. The hiding ship has full use of its other defenses while using its camouflage field (assuming that they have not been damaged), but it may not fire weapons during the same turn in which its camouflage field was active.
As a safety precaution, self destruct mechanisms are intentionally difficult to enable, and even more difficult to disable. Enabling the self destruct device requires an Agility + Engineering roll vs. 12. A self destruct device can be disabled during the first half of its countdown with a successful Agility + Engineering roll vs. 15.
 
 
===Enhanced Sensors===
 
Science vessels and scout ships often have enhanced sensors to assist with their missions. If a ship is equipped with enhanced sensors, the sensor operator gains a +{{KM4_SKILL_BONUS}} bonus on any sensor-related skill rolls.
 
===Medical Bays===
 
The rating of a ship's medical bay is added to a medical staff member's Medicine (Reason) when treating a patient. A standard medical bay on a starship is equipped to treat a variety of minor injuries and ailments, and normally has a rating of 1. Massive civilian cruise ships often have an enhanced medical bay, with a rating of 2, while large military vessels usually have a fully equipped hospital facility, with a rating of 3.
 
===Megaweapon===
 
In addition to the ship's other weapons, the ship has a single massive weapon around which the rest of the ship is built. This megaweapon can only be fired once every ten rounds (one minute) at a single target. When attacking with the megaweapon, the Engines rating of the attacking ship is added to its Weapons rating.
 
===Overthrusters===
 
An overthruster is a colliding beam accelerator which creates intermediate vector bosons from the annihilation of electrons and positrons. If a ship is equipped with overthrusters, the pilot gains a +{{KM4_SKILL_BONUS}} bonus on any pursuit-related or evasion-related Piloting rolls.
 
===Point Defense Systems===
 
Point defense systems offer an additional defense against [[ZeroSpace_4e_EN:Starships#Ship_Classifications|fast attack craft]] (bombers, fighters, and interceptors). If a ship with a point defense system is being attacked by a fast attack craft, the defending ship gains a +{{KM4_SKILL_BONUS}} bonus on its defense roll.
 
===Tractor Beams===
 
Tractor beams are gravitic weapons intended to prevent the target from moving. Using a tractor beam generally requires a Warfare (Reason) roll plus the rating of the tractor beam. The difficulty (DV) is based on the defending pilot's Warfare (Reason) and the defending ship's Defenses rating.
 
Tractor beams do not deal points of Hull damage to the target. Instead, on a successful roll, the Hull rating of the attacking ship is subtracted from the Engines rating of the defending ship for as long as the tractor beam is focused on the target. If the target's effective Engines rating is reduced to zero, the target ship is unable to move.


Escaping from a tractor beam can be accomplished one of three ways: the tractored ship can move beyond the [[ZeroSpace_4e_EN:Starships#Range_Bands|effective range]] of the tractor beam (based on the rating of the tractor beam); the tractored ship (or another ship) can reduce the Hull of the ship with the tractor beam to zero, causing the tractor beam to shut off; or the fleeing ship (or another ship) can break the tractor beam's hold by successfully [[ZeroSpace_4e_EN:Starships#Targeting Specific Systems|targeting the "cargo/other equipment" system]] of the ship with the tractor beam.
A starship which self destructs will explode with tremendous force, utterly destroying the starship and severely damaging any nearby starships. Any vessel within short range of the exploding starship will take points of damage equal to the Engines of the exploding starship, bypassing the target's defenses.

(NOTE: This is a work in progress.)

If this were a starship combat game, rather than a space fantasy roleplaying game, we would make this section much more complicated. A starship's mass would make Piloting rolls more difficult, different weapons would be more or less effective against different defenses, and so on. But this is not a starship combat game, so this section is as simple as we could make it.

Regrettably, it's still pretty complicated.

Overview

Starships allow player characters to go from place to place in the galaxy, seeing people, places, and things which are too far away or too dangerous to visit without one. Starships also serve as a mobile base for the player characters, providing a place to store their stuff and recuperate between adventures.

Parts Of A Starship

Bridge

The bridge is where the pilot controls the starship's movement. It typically has stations for the captain of the starship and a number of staff officers. On medium-size warships, the bridge may also include combat information center functions; on larger warships, the combat information center is a separate location.

Engine Room

The engine room provides more precise control of the power core and the warp engines, and may allow direct observation of them (behind appropriate safety shielding, of course). Larger starships may have several engine rooms, and the largest starships might have dozens.

Fabricators

Most starships of Class 3 or higher have fabricators. The fabricators on smaller starships are adequate for day to day needs, such as meals and simple shipboard items. Larger starships may have specialized fabricators for the med bay, a more complete meal library, and engineering fabricators for most replacement parts. The largest starships have a complete suite of industrial fabricators, and are capable of creating parts to build entire starships. If a starship also has an Exotic Particle Synthesizer Console, it can even construct power cores and warp engines.

Grav Plates

The perception of gravity on starships is provided by grav plates. Grav plates operate on the same electrogravitic principles as the thrusters used when a starship is near a planetary surface. Grav plates are mechanically simple and generally quite reliable: if a starship's grav plates have failed, something has gone terribly wrong.

Hangar

Starships of Class 4 or higher typically have a hanger. This hangar can accommodate either a single starship two Classes smaller (typically a squadron -- see Squadrons, below).

Hold

All starships have at least one hold. The dimensions of the hold may vary considerably, from the size of a lunchbox to that of a small moon. The hold might have gravity plating and a breathable atmosphere, depending on its intended use, but it is not designed for habitation.

Med Bay

Every starship has a medical facility, although the size and sophistication of the facility varies a great deal. On smaller starships, a medical pod or "autodoc" can heal most injuries, or keep the patient alive until more advanced treatment may be found. Larger starships may have multiple, specialized medical pods, along with more advanced diagnostic and treatment equipment. The largest starships have full hospital facilities, although it is still called the "med bay".

Passageways

On Restoration Era starships, passageways are usually considered wasted space, and are made no larger than necessary: rarely wider than three meters.

On Panglossian Era starships, particularly Old Commonwealth starships, passageways were much larger. Class 3 Old Commonwealth starships had passageways two meters wide, while Class 5 and larger starships had passageways at least six meters wide and four meters tall.

Starships also have smaller access corridors used for maintenance. Such corridors are typically just wide enough to crawl through on Restoration Era starships, but are large enough for two engineers to work comfortably on Panglossian Era starships.

Power Core

Starships generally use hybrid fusion-singularity reactors. The fusion furnace, the singularity containment system, and all associated components are referred to as the starship's "power core".

Power cores are "fired up" or "brought online" to make them ready for use, and "shut down" or "taken offline" to render them inert. Bringing a power core online typically takes 6 hours, or 2 hours if the power core has been in use within the last 24 hours. Taking a power core offline takes less than a second, but there are numerous safety checks which follow, taking around an hour.

Screens

"Screen" is a catch-all term for the ubiquitous audiovisual displays aboard a starship. Holograms can be "brought up" or "shut down" with a gesture, or higher-resolution images can be displayed on physical monitors. The display is often augmented to provide additional data: sounds may be added to represent the activity of an object on the screen, such as the firing of weapons or the explosion of an engine; weapons such as particle beams, which are invisible to the naked eye, are spectrum-shifted to be visible; and so on.

Sensors

XXX short range is weapons range medium range is sensor range long range is beyond most sensor's range

Thrusters

A starship's conventional engines, used for moving the starship through relatively normal space, are referred to as "thrusters". Electrogravitic thrusters are typically used when within a kilometer of a planetary surface or other inhabited area, with fusion thrusters engaged once the starship leaves this safety region. A typical starship can lift off from a planet and clear the atmosphere in a few minutes.

Warp Engine

Warp engines create a microscopically-thin Lorentzian manifold of spacetime around a starship -- typically called a "warp bubble". This allows the starship to remain relatively motionless while also achieving velocities which are relatively relativistic.

Warp engines are "fired up" or "brought online" to make them ready for use, and "shut down" or "taken offline" to render them inert. Bringing a starship's warp engines online typically takes 3 hours, or 1 hour if the warp engines have been in use within the last 24 hours. Taking the warp engines offline takes less than a second, but there are numerous safety checks which follow, taking around an hour.

Before the warp engines are engaged, a destination is selected and the anticipated arrival time is calculated. Engaging the warp engines activates the Lorentzian manifold generator and moves the starship toward the pre-set destination. The warp engines are typically disengaged at a pre-set arrival time, which nearly always puts the starship where the navigator expected. However, the warp engines may be disengaged manually, placing the starship into relatively normal space somewhere between the starship's origin and its pre-set destination.

While the warp engines are engaged, the starship is unable to communicate with or interact with the universe outside of the warp bubble.

Windows

What a crew member sees in a window may be augmented with distinct sounds or overlaid visuals, such as a target's range or mineral composition. Sophistication of the display and any audio accompaniment varies by starship and manufacturer. Some starships have a "privacy" mode, which looks the same from the inside, but looks like a glowing white haze from the outside. And of course, a starship's windows automatically compensate for the luminosity of what is outside the window.

Starship Attributes

As with characters, a starship's attributes are ranked from 1 (the smallest starships) to 10 (the largest starships), and can't be reduced below zero or above 10. A starship has one core attribute, its Class, and five secondary attributes, its Consoles, Engines, Hull, Shields, and Weapons. A starship's Class determines the starting value of its other attributes, the size of its crew, and so on.

Table: Starship Classes, New Commonwealth (Restoration Era)
Attribute Starting Value Description
Consoles Class The number of consoles a starship may have equipped.
Engines Class Determines the starship's travel time.
Hull Class Determines how many points of damage the starship may take.
Shields Class Reduces the points of damage the starship takes from a successful attack.
Weapons Class Determines how many points of damage the starship may deal.
Armor 1/2 Hull (minimum 1) Reduces the points of damage the starship takes from a successful attack.


Each attribute can be modified in a number of ways, from a minimum of 0 to a maximum of 10. Here are some examples of modifying the rating of a starship's Consoles (there will be a full list further down):

  • The Experimental subclass (X) increases Consoles by 1.
  • The Escort starship type reduces Consoles by 1.
  • A Bha'atar-manufactured starship reduces Consoles by 1.
  • A Zniss-manufactured starship increases Consoles by 1.

Consoles

Consoles are a form of starship equipment. As with personal equipment, a console's equipment bonus replaces or adds to a player's skill roll (see Skills.

Some consoles provide additional capabilities to the starship (see Starship Consoles, below).

Engines

The Engines attribute reflects the capacity of a starship's power core and the maximum strength of its electrogravitic thrusters, fusion thrusters, and warp engines.

Hull

The hull of a starship is one of its toughest parts. Only portions of the power core are more durable. A starship which is large or densely constructed will have a higher Hull than one which is smaller or less dense.

Shields

Energy shields on a starship serve two purposes. The primary reason for shields is to protect the starship from hazards such as micrometeorites, ambient high-energy particles, and other interstellar debris while traveling in realspace. No roll is required for this, as it's an automated and highly redundant function, much like life support.

The secondary purpose of shields is to protect the starship against hazards such as exploding stars and attacks from other starships. The rating of the Shields is subtracted from the points of damage dealt by a successful attack.

Energy shields lose effectiveness as they withstand attacks. A starship's shields grant their full protection value against the first successful attack in a scene. The second attack against a starship in a scene, the shields grant one less than their full protection value. This continues until the protection value granted by the shields is reduced to zero (the shields "go down", in common parlance). The shields will be restored to full effectiveness after the fight is over, when the shield coils have had a chance to recharge.

The starship's engineering team may also attempt to restore the shields during combat (see Repairing The Starship, below).

Weapons

The number of attacks a starship may make per round is equal to its Weapons. The starship may be able to make additional attacks provided by its consoles, but those are handled separately (see [ZeroSpace_4e_EN:Starships#Starship_Consoles|Starship Consoles]], below).

Note that the starship's Weapons attribute is not the physical number of its weapons. A starship with Weapons 5 might have only two physically distinct weapons, or it might have twenty, depending on the design, size, and placement of the weapons themselves. A starship's weapons may be described however the GM likes, but this is merely flavour, and makes no actual difference in combat. Here are some examples, but you are not restricted to these options.

Table: Typical starship weapons
Ship Class Typical weapons
1-2 Rail cannon, turbolaser beam, neutron missile
3-4 Particle cannon, pulsar beam, fusion missile
5-6 Plasma cannon, disruptor beam, antimatter missile
7-8 Meson cannon, hellbore beam, singularity missile
9-10 Nemesis cannon, planetary defense beam array, warp missile


Armor

Armor reduces the points of damage the starship takes from a successful attack. The starting value for a starship's Armor is one-half its Hull rating (round down, even if the fraction is more than one-half, to a minimum of 1). The starship's Armor is subtracted from the points of damage dealt by a successful attack.

Starship Class

The categorization and nomenclature of starships is a field rife with inconsistency. The Old Commonwealth had hundreds of starship classes, and the New Commonwealth is on its way to matching that achievement. In contrast, the Bha'atar have only two main classes of starship: warships ("starhawks", in Bha'atar parlance) and support ships ("rousters", in Bha'atar parlance).

This is not a system of nomenclature that lends itself easily to direct comparisons, so the game system will refer to the starship classifications below. Any resemblance between this system and that used by any interstellar fleet is purely coincidental.

Table: Starship classes, New Commonwealth (Restoration Era)
Starship Class Typical Crew Length (m)
Min Full From To
9 Star Fortress 100,000 350,000 140,000 160,000
8 Leviathan 10,000 35,000 3,000 5,000
7 Titan 1,000 3,500 300 500
6 Battlecruiser 128 448 180 400
6 Battle Escort (Battleship) 64 224 120 270
5 Heavy Cruiser 96 336 150 300
5 Heavy Escort (Destroyer) 48 168 100 200
4 Light Cruiser 32 112 120 200
4 Light Escort (Frigate) 16 56 80 140
3 Corvette (Courier, Patrol Ship, Scout) 8 28 30 120
2 Littoral Vessel (Customs, Police, System Defense) 2 7 20 90
1 Small Craft (Bomber, Fighter, Interceptor) 2 7 15 50


Subclass X: Experimental

An experimental starship (indicated with an "X" after its Class) may have one more console than its Class would indicate. For example, a Class 3X corvette could have four consoles installed.

Starship Class And Crew

On very small starships, a single crew member may be responsible for some or all of the starship's systems. In a fighter, for example, the pilot, the navigator, and the engineer could all be the same person. On larger starships, these responsibilities are usually distributed among specialists: the starship may have several pilots, navigators, and engineers, as well as dedicated scientists, sensor operators, and medical professionals.

"Minimum crew" refers to the absolute minimum number of crew required to operate a Restoration Era starship at full effectiveness for one shift. "Full crew" can vary considerably. The number of full crew given above is for a New Commonwealth (Restoration Era) starship, where the crew complement is generally three and a half times the minimum crew: sufficient for three shifts and an occasional off-duty day for each crew member. Bha'atar starships have the same number of minimum crew, but operate two shifts continuously without any off-duty days. A typical Bha'atar destroyer has 96 crew members (double the minimum crew for a destroyer). However, Bha'atar tours of duty are typically shorter than those in the New Commonwealth.

Old Commonwealth Crew Sizes

Old Commonwealth (Panglossian Era) starships could operate with less than one-quarter the crew of a comparable New Commonwealth starship, thanks to extensive automation and the starship's AI, or "geist". Old Commonwealth starships Class 4 and larger normally carried six times the minimum amount of crew; Old Commonwealth crews worked fewer, shorter shifts than New Commonwealth crews are expected to work. A typical Old Commonwealth heavy cruiser had a minimum crew of 24 and a full crew complement of 144, compared to 96 and 336 for a New Commonwealth heavy cruiser. Despite the smaller crews, Old Commonwealth starships were as large if not larger than equivalent New Commonwealth starships, and their interiors were cavernous by comparison.

Starship Types

Some common starship types modify a starship's attributes.

SIDEBAR: Standard Cargo Units

A standard cargo module in the ZeroSpace universe is 28m x 15m x 15m -- 6300 cubic meters. This is referred to in naval architecture terms as "6300 tonnes". Most people assume that this is because 6300 cubic meters of water has a mass of 6300 tonnes.

Fun fact! A standard cargo module holds one Divine Legion in cryostasis -- 1000 genetically modified, fanatically loyal soldiers of the Infinite Dominion in full armor (weapons and other equipment shipped separately).

Starship Subtypes

Some common subtypes further modify a starship's attributes.

Flight Deck

Starship Combat

Sometimes, people in other starships will shoot at the players' starship, leaving the player characters no choice but to return fire. Here is how that works.

Initiating Conflict

As with normal combat, conflict begins when one side decides to stop talking and start shooting. If a character wishes to initiate a conflict, the captain of each starship makes a Presence + Survival roll. If one or more starships get the drop on their opponents (an ambush, for example), the captain of a starship with a situational advantage gains a +3 bonus to their Presence + Survival roll. Actions proceed each round from the crew whose captain rolled highest to the crew whose captain rolled lowest, with the characters on each starship taking their turns in whatever order they would like. A starship, like any piloted vehicle, moves when its pilot takes their turn. When every character has had the opportunity to take a turn, the starship with highest initiative goes again, and so on until the conflict has ended.

While the player characters are handling the important tasks, the starship's other crew (if there are any) are firing weapons, performing scans, dealing with the wounded, and making repairs, but it all goes more or less as planned and has no impact on the outcome of the conflict.

The environment goes last in a round. The status of asteroids or other uncontrolled objects are determined after after all of the characters have had the opportunity to take their turn.

Rolling Dice

2d6 + [attribute] + [skill bonus or equipment bonus]

In game terms, starships operate much like characters' personal equipment. Each crew member may use a standard action to make a skill roll, as usual. The player rolls their dice, counts the dots, adds the character's relevant attribute, and adds their skill bonus or their equipment bonus. If a character has an appropriate skill and the appropriate equipment, use whichever bonus is larger, and add +1.

There are three main tasks a crew member can undertake during starship combat: piloting the starship, firing the weapons, and repairing the starship.

Squadrons are a special case. Rather than a single starship, a squadron is an arbitrary number of small starships. If a squadron is controlled by the player characters, the characters may assume the roles of pilot, gunner, or engineer however they like, and their rolls affect the squadron as a whole. The squadron loses ships as it takes damage, but it's assumed the player characters are in craft that survive the battle.

Piloting The Starship

Piloting Maneuvers

At the beginning of their turn, the pilot may declare that they are using one of the following maneuvers. Choosing a maneuver is optional, and does not require an action or a roll.

Damn The Torpedoes: If the pilot declares "Damn The Torpedoes", they incur a +3 DV penalty on their Piloting rolls and defense, but the crew on the same starship gains a +3 bonus on any Ranged Combat rolls against other starships. These bonuses and penalties last until the beginning of the pilot's next turn.

Evasive Maneuvers: If the pilot declares "Evasive Maneuvers", they gain a +3 bonus to their Piloting rolls and defense, but the crew on the same starship incurs a +3 DV penalty on any Ranged Combat rolls against other starships. These bonuses and penalties last until the beginning of the pilot's next turn.

Piloting Tasks

Each round, the pilot of each starship may attempt an Agility + Piloting roll to direct the starship's movement.

Table: Typical starship Piloting tasks
Task Roll Difficulty
Tactical Maneuvering Agility + Piloting vs. 12
Flee Pursuit Agility + Piloting vs. 8 + the pursuing pilot's Agility + Piloting
Avoid Obstacles Agility + Piloting vs. 12
Set Destination Reason + Piloting vs. 12/15

'Tactical Maneuvering: If the pilot succeeds at this roll, the crew on the same starship gains a +1 bonus on any Ranged Combat rolls against other starships. This bonus lasts until the beginning of the pilot's next turn.

'Flee Pursuit: Fleeing pursuit is treated as an extended task. If one pilot wants to leave the conflict but the other pilot doesn't, the fleeing pilot uses a standard action on their turn to attempt an Agility + Piloting roll vs. 8 + the pursuing pilot's Agility + Piloting. If the fleeing pilot achieves three successes and their starship has at least 1 Hull point remaining, the fleeing pilot eludes the pursuing pilot, and their starship leaves the conflict.

'Avoid Obstacles: If the pilot succeeds at this roll, their starship is safe from collisions with unguided objects until the beginning of the pilot's next turn.

'Set Destination: The difficulty of this roll is typically 12, or 15 if the starship is engaged in combat. If the pilot succeeds at this roll, they set their starship's course and engage the warp engines, secure in the knowledge that everything will go as planned and the engines will disengage at the proper time, returning the starship to relatively normal space near the intended destination. If something goes wrong, there is an alarm, but navigation errors are rarely fatal.

Firing The Weapons

The number of attacks a starship may make per round is equal to its Weapons rating. The starship may be able to make additional attacks provided by its consoles, but those are handled separately (see [ZeroSpace_4e_EN:Starships#Starship_Consoles|Starship Consoles]], below).

To make an attack with one of the starship's weapons, a crew member must use a standard action to attempt an Agility + Ranged Combat roll.

Attacker (AV) vs. Target (DV)
2d6 + Agility + Ranged Combat 8 + Agility + Piloting


If the attacker's Action Value meets or exceeds the target pilot's Defense Value, the attack succeeds.

Hull Damage

If the attacker's roll succeeds, the player rolls 1d6 and adds the Weapons rating of their starship. The target starship's Shields and Armor are deducted from this amount, and the remaining points of damage are subtracted the target's starship's Hull.

Damage minus Protection
1d6 + Weapons Shields + Armor


When a starship takes points of damage, the points are temporarily subtracted from its Hull. A starship which has been reduced to zero Hull is disabled: it is out of the fight, and it will probably require extensive repairs. Hull may not be reduced below zero.

Starship weaponry is much more powerful than the weapons mounted on vehicles or carried by individuals. If a starship weapon is brought to bear against a vehicle, the damage roll is increased by 3. If a starship weapon is brought to bear against an individual, the damage roll is increased by 6. Conversely, if a vehicle weapon is brought to bear against a starship, the damage roll is decreased by 3 (minimum 0). If an individual weapon is brought to bear against a starship, the damage roll is decreased by 6 (minimum 0).

Repairing The Starship

Normally, the crew of a damaged starship may repair half of the starship's lost Hull (rounded down, minimum 1) by working on it for about a day. Barring some extraordinary event, a starship's Hull will be completely repaired after a week in a stardock.

Engineering Maneuvers

At the beginning of their turn, the chief engineer may declare that they are using one of the following maneuvers. Choosing a maneuver is optional, and does not require an action or a roll.

Auxiliary Power To Engines: If the chief engineer declares "Auxiliary Power To Engines", the starship gains a +1 bonus to its Engines (maximum of 10), but it incurs a -1 penalty on its Shields and Weapons (minimum of 1). These bonuses and penalties last until the beginning of the chief engineer's next turn.

Auxiliary Power To Shields: If the chief engineer declares "Auxiliary Power To Shields", the starship gains a +1 bonus to its Shields (maximum of 10), but it incurs a -1 penalty on its Engines and Weapons (minimum of 1). These bonuses and penalties last until the beginning of the chief engineer's next turn.

Auxiliary Power To Weapons: If the chief engineer declares "Auxiliary Power To Weapons", the starship gains a +1 bonus to its Weapons (maximum of 10), but it incurs a -1 penalty on its Engines and Shields (minimum of 1). These bonuses and penalties last until the beginning of the chief engineer's next turn.

Engineering Tasks

Each round, each engineer on a starship may attempt a Reason + Engineering roll to repair the starship and restore disabled systems.

Table: Typical starship Engineering tasks
Task Roll Difficulty
Jury Rig Reason + Engineering vs. 8 + Hull + points of damage
Restore Shields Reason + Engineering vs. 8 + Shields + lost Shields
Break Free Reason + Engineering vs. 8 + Class + Console Mk

Jury Rig: To restore a single lost point of damage during combat, an engineer must use a standard action to attempt a Reason + Engineering roll against 8 + Hull + points of damage their starship has taken. For example, if the starship normally has Hull 3, and has taken 2 points of damage, the DV of the roll is 8 + 3 + 2 = 13. If the engineer's roll is successful, one point of Hull is restored to the starship. However, the starship should visit a starbase for proper repairs as soon as possible.

Restore Shields: To restore a single lost point of Shields during combat, an engineer must use a standard action to attempt a Reason + Engineering roll against 8 + Shields + lost Shields of their starship. For example, if the starship normally has Shields 3, and has lost 2 points of Shields from successful attacks, the DV of the roll is 8 + 3 + 2 = 13. If the engineer's roll is successful, one point of Shields is restored to the starship.

Break Free: To break the starship out of an attack with an ongoing effect, such as a Tractor Beam Console, an engineer must use a standard action to attempt a Reason + Engineering roll against 8 + Class + Console Mk of the attacker. If the engineer's roll is successful, the starship breaks free from the ongoing effect.

Starship Consoles

Consoles are a form of starship equipment. As with personal equipment, a starship console's bonus replaces or adds to a player's skill roll.

Panglossian Era Consoles

Panglossian Era starships had two additional consoles, both at the same quality as the starship's Class, up to mark V (for example, on a Class 3 starship, these two consoles would be mark III; on a Class 7 starship, these two consoles would be mark V). First, each Panglossian Era starship had a Geist Management Console permitting the starship's AI, or "geist" (a crew position), to manage the starship's myriad automated systems (this console was not removable, although it could be upgraded). Panglossian Era starships also had a Wormhole Network Interface Console , which granted the starship the ability to use the wormhole network. These consoles were in addition to the consoles a starship would be permitted due to its Class. For example, a Class 3X Panglossian Era corvette could have six consoles installed: these two, three more due to its Class, and an additional console due to the "Class X" rating.

Restoration Era Consoles

Tractor Beams

Tractor beams are gravitic weapons intended to prevent the target from moving.

Tractor beams do not deal points of damage to the target. Instead, on a successful roll, the Engines rating of each starship is subtracted from the Engines rating of the other starship for as long as the tractor beam is focused on the target. If either ship's effective Engines rating is reduced to zero, the starship is unable to move.

Other Equipment

Emergency Self Destruct

Self destruct systems are present aboard most commercial and military starships. Initiating the self destruct on a spacecraft disengages its engine coolant system, quickly causing the vessel's power core to overload and explode, destroying the spacecraft after a set time period has elapsed (usually 10 minutes).

As a safety precaution, self destruct mechanisms are intentionally difficult to enable, and even more difficult to disable. Enabling the self destruct device requires an Agility + Engineering roll vs. 12. A self destruct device can be disabled during the first half of its countdown with a successful Agility + Engineering roll vs. 15.

A starship which self destructs will explode with tremendous force, utterly destroying the starship and severely damaging any nearby starships. Any vessel within short range of the exploding starship will take points of damage equal to the Engines of the exploding starship, bypassing the target's defenses.
