Three, two, one . . . Blast off!
GURPS Spaceships is the long-awaited companion to GURPS Space, presenting rules for TL7-12 spacecraft, from tiny lifeboats to giant dreadnoughts. It covers spaceship design, travel, and operations, along with a (mapless) space combat system.
The ship design and operation rules in GURPS Spaceships are more abstract than those found in GURPS Vehicle Design or GURPS Traveller: Interstellar Wars . . . but they're much faster, with a minimum of math and a maximum of colorful options. It takes only minutes to build even the largest spaceship . . . and wrapped around the design system are basic space travel and combat systems to get you into space right away.
GURPS Spaceships doesn't include detailed finance, trade, or hex-grid based combat rules . . . but these are on the way! It's the core book in a series whose other volumes will present examples of ready-to-use spacecraft and comprehensive rules for commercial space flight, warfare, exploration, ports, industry, and other aspects of space travel.
GURPS Spaceships requires only the GURPS Basic Set, but GURPS Space is highly recommended for its guidelines on stardrives, characters, campaigns, and settings.
