StarCraft Gamma World: Starships

Starship Combat
Enemy starships are added to combat encounters much the same way as standard creatures, each contributing their designated XP to the encounter total. Enemy starships, obviously, are only appropriate in encounters where they can threaten and interact with starships under the command or protection of the adventurers. Non-Combat vessels are ships that do not possess any weapons that are dangerous to other ships, but often represent support craft, transports, civilian vessels, and other targets of opportunity.

Vessels in combat are considered to be continually moving under their respective propulsion systems and inertia, and do not require a specific action to control. Starship positions relative to each other are not physically represented, but are instead assumed to be moving about on the battlefield at some distance to each other.
To attack an enemy starship, a character must be at a command console, located somewhere on each vessel. Command consoles can be any specific form on a starship, such as a helm wheel or weapons’ console. While at the command console and operating the starship, a character is prone. A character at a command console may spend a minor action to make offensedefense, or feint checks against one enemy vessel, using skills deemed appropriate by the Game Master, similarly to a Skill Challenge. Interaction is commonly used for feint checks, Mechanics is often used for defense checks, and History can also be used to call upon military tactics for offense, etc. Starships have one usable command console per 50 hit points, rounded down.

* A successful check against a starship’s offense DC deals 2d8 damage to an enemy ship.  Non-combative ships cannot make this check until they have been ungraded with a basic weapon system.
* A successful check against a starship’s defense DC reduces the next damage your ship takes from that enemy by 5.
* A successful check against a starship’s feint DC provides a +2 bonus to the next three checks you make with your ship.
* Alternatively, a successful check against a starship’s feint DC positions your starship close enough to the enemy vessel for boarding, or evades an enemy boarding attempt.
* At the end of each round, each enemy vessel deals its damage to a single allied vessel of the adventurers, and then declares whether it will attack again or attempt to board one of the adventurer’s vessels. If the enemy vessel attempts to board an allied vessel of the adventurers, a character onboard the allied vessel must make a successful feint check to evade the boarding enemy vessel.
* A successful boarding attempt allows occupants on both vessels to move between the  two starships as a move action, using an extendable docking collar.

At the start of each StarCraft Gamma World campaign, the adventuring party is given one unarmed scout craft for use in travelling between adventures.

Starship Upgrades

There are multiple upgrades can be applied to the adventurers’ starship. Players are encouraged to create new and innovative upgrades to their vessels, and Game Masters are encouraged to allow these creative outlets and work them into the ongoing story. The Game Master may award starship upgrades as deemed appropriate to the campaign story in place of distributing an item of advanced equipment.

* Basic Weapons System: Allows a non-combat vessel to make checks against an enemy starship’s offense DC ; deals 2d8 base damage
* Upgrade Weapons:
 deal +5 damage
Upgrade Weapons: damage is reroll all damage rolls that show a 1
Upgrade Maneuvering: +2 to offense, defense or feint (can only upgrade each ability once)
Increase Ship Size/Upgrade Hull: +25 HP (Max 250 HP)

Boarding Parties

Ship-to-ship boarding parties are assumed to invade an enemy vessel at an area close to the command center of the vessel, through either an accessible airlock or by cutting directly through the starship hull. Each enemy starship has guards permanently stationed to repel invaders. A starship will typically have one Minion pilot, on Minion officer, and 1 Standard guard per ship size, of a level equal to the starship. These creatures do not contribute to total XP of the encounter and are considered part of the vessel they are on.

In addition, a starship can carry a boarding party to go on the offensive and bring the fight to the adventurers' front door. A boarding party attempting to take the adventurers' starship can make for the beginnings of an excellent encounter. Unlike stationary guards, offensive enemy boarding parties add their experience point value to the total for an encounter.

Travel, Repairs & Supplies

The StarCraft Gamma World setting focuses on high adventure and exploration, and does not bother itself with the trivialities of day-to-day function. All ship hit points are repaired at the end of an extended rest, and a precise catalogue of food and fuel expenditures is never made, unless it is plot-relevant.

Adventuring Tips

It is assumed that the adventurers are operating as a rogue force, raiding the vessels of government-back navies when they can. As such, their opportunities for selling captured starships become more limited, as buying misbegotten goods can be problematic for the non-heroic merchants the adventurers come across. While there's nothing wrong with making a profit by raiding, but it's usually a more fun adventure to steal the cargo from an old Dominion frigate than it is to mundanely scavenge and pawn junked ships.

Over time, adventurers may find themselves in possession of a number of small starship comprising their own little fleet. Operating such a fleet makes each starship vulnerable to a large boarding party, as the adventurers must spread themselves across the entire fleet to protect it. A boarding party of Protoss Zealots will make short work of any ship with only a single adventurer piloting it.
