GURPS Infinite Worlds (original) (raw)

GURPS Infinite Worlds is a supplement for the Fourth Edition of the GURPS role-playing game, published by Steve Jackson Games in 2005 and written by Kenneth Hite, Steve Jackson, and John M. Ford. It expands upon the campaign setting of conflict between the Infinity Patrol, which is the dimension-jumping agency on "our" Earth, referred to as Homeline, and Centrum across a multiplicity of alternate history Earths. This was presented in the Fourth Edition GURPS Basic Set (and originated in the Third Edition supplements GURPS Time Travel, GURPS Alternate Earths, and GURPS Alternate Earths II).
