GURPS Space

GURPS Space is a supplement that expands on the core GURPS Fourth Edition rules. While it provides extensive content for science fiction settings, players will need the GURPS Basic Set to fully utilize the rules and character creation options presented.

This book is known for its highly detailed and modular approach to world-building, allowing Game Masters to construct virtually any type of science fiction setting, from hard sci-fi to space opera, with consistent rules. It provides extensive tools for creating unique alien races, starship designs, and interstellar societies rather than a pre-defined universe.
