GURPS Basic Set: Campaigns combines information from the Third Edition GURPS Basic Set and GURPS Compendium II -- plus our new core setting, with infinite possibilities for timeline-hopping adventure! (You don't have to play in the core setting -- there isn't some game-altering metaplot -- but it's there if you want it.) This 240-page, full-color hardcover contains everything a GM needs to create and run a GURPS Fourth Edition campaign.
