Earth is dead -- but in the last years before the catastrophe, the starship Unity was launched. It carried a few thousand colonists to the nearby Alpha Centauri system, where they were to build a new Earth on the world called simply Planet. Then disaster struck. Mutiny split the crew into factions, each with its own plans for the new world. The colonists were plunged into a centuries-long struggle against hostile nature, horrific alien life-forms, and each other. Only one faction could win control over Planet and the destiny of humanity . . . GURPS Alpha Centauri is a sourcebook based on the award-winning computer game Sid Meier's Alpha Centauri. It includes everything you need to recreate the story of humanity on Planet, from the desperate days after the landing to the edge of human transcendence.
