It was actually a very easy conversion. I'm still tweaking the vehicles, but they should be ready by the 12th, in time for the game. You asked for examples, so here's the first. True20 uses a relatively small number of "roles," or classes, which gain four feats at first level and one every additional level. In addition, each character has a "background," usually representing his race.
True20 Starcraft has three general roles: Grunt (full BAB warrior type), Tech (cleric BAB, high-skill expert type), and Psion (wizard BAB, able to use psychic powers).
Backgrounds represent the character's basic military training rather than his race, since all PCs will be Terran. The following is an excerpt from the True20 Starcraft Terran Handbook:
training backgrounds
Every Terran in the Dominion’s military receives intensive, specialized training to prepare him for the ravages of service. Choose one such background at first level, representing the type of training your character has received.
Marine – The marine is the basic infantry unit of the Terran Dominion military. Highly trained from their youth, they neglect all else in the name of combat prowess. Marines can be found in nearly every engagement the Terrans have ever participated in, from large-scale assaults to discreet, surgical operations.
Bonus Feats: Combat Armor Training, Weapon Training (Gauss Rifle)
Equipment: C-14 “Impaler” Gauss Rifle, Standard Combat Armor, Stim Packs (5)
Firebat – The Terran Firebat is an armored shock trooper known for its trademark flamethrower. Their ranks are comprised mainly of those individuals who find difficulty fitting in to Dominion life and have had to be “reconditioned.” Since the first discovery of Zerg xenomorphs, the number of Firebats in service to the Dominion has increased dramatically due to their effectiveness in close combat.
Bonus Feats: Combat Armor Training, Weapon Training (Perdition Flamethrower)
Equipment: Light Flamethrower, Firebat Combat Armor, Stim Packs (5)
Medic – The combat medic is one of the most vital parts of any Terran strike force. Trained in first aid and specialized in the use of the Terran Apollo™ combat medical apparatus, they keep the other forces fighting. Since the Apollo™ was introduced, the effectiveness of Terran ground troops has nearly doubled due to the work of medics.
Bonus Feats: Combat Medic, Skill Focus (medicine)
Equipment: Assault Pistol, Apollo™ Combat Medical Apparatus, Light Protective Gear, Optical Flares (3)
Pilot – The pilot specializes in operating one of the Terrans’ combat vehicles. Whether he is at the helm of a Goliath, a Siege Tank, a Wratih, or even a Battlecruiser, the pilot is truly a fearsome foe. While he lacks the combat skill of a marine or firebat on his own, within his vehicle of choice he proves his true worth.
Bonus Feats: Vehicular Combat, Skill Focus (pilot)
Equipment: Assault Pistol, Light Protective Gear, Optical Flares (3)
Engineer – The engineer is there when an obstacle stands in the way of the Terran military machine. He is adept in structural technology, well-versed in explosives and ballistics. When the Terrans need heavy personnel weaponry or demolitions, they call on the Corps of Engineers.
Bonus Feats: Talented (Demolitions, Disable Device), Weapon Training (Rocket Launcher)
Equipment: Assault Pistol, Gungnir Rocket Launcher with Rockets (4), Grenade [Frag or Shock] (3), Terran Advanced Demolition Compound (3), Light Protective Gear
Ghost – The Ghost is the Terrans’ psionic special operations unit. Trained from infancy, Ghosts are humans with high psionic potential who are directed and taught to use it on the battlefield. With the ability to read thoughts, enhance their physical abilities, and render themselves invisible to those with weaker minds, Ghosts are used primarily for swift, specific strikes where larger forces prove too cumbersome.
Bonus Feat: Mind Touch*, Weapon Training (C-10 Canister Rifle)
Equipment: Light Stealth Armor, C-10 Canister Rifle, Assault Pistol
More examples will be forthcoming. The next will likely be a sample character sheet. Hope to see you all there.
