GURPS lets you be anyone you want in any world you can imagine. Elves in fantasy, Musketeers in historical France, action heroes or superheroes in today's world, futuristic space explorers, cartoon characters . . . GURPS provides tools for all this and more. That's why it has been the premier universal roleplaying game for four decades!

When GURPS, Fourth Edition came out in 2004, those tools needed two books: Characters combined some of the GURPS Basic Set, Third Edition with GURPS Compendium I, while Campaigns merged the rest of the Basic Set with swaths of GURPS Compendium II. Ever since, gamers have asked us to put it all in one place.

The wait is over! This 592-page book – with a new cover and a two-column layout – contains everything from Characters and Campaigns, lightly edited for internal consistency, errata fixes, sensitivity, and to bring a few bits of information up to date. As a bonus, it includes 25 pages of rules highlights from GURPS books and Pyramid articles published between 2004 and 2025.

The GURPS Basic Set, Fourth Edition Revised is not a new edition. It is fully compatible with all Fourth Edition material in print, and all text appears on the same pages, preserving page references.
