Three, two, one . . . Blast off!
GURPS Spaceships is the long-awaited companion to GURPS Space, presenting rules for spacecrafts of every size and function. It covers spaceship design, travel, and operations, along with a (mapless) space-combat system.
The ship design and operation rules in GURPS Spaceships are quick to learn and easy to put into action, with a maximum of colorful options. It takes only minutes to build even the largest spaceship. And the design systems are augmented by straightforward space travel and combat systems, to get you into space right away.
GURPS Spaceships requires only the GURPS Basic Set, but GURPS Space is highly recommended for its guidelines on stardrives, characters, campaigns, and settings.
