GURPS Infinite Worlds

GURPS Infinite Worlds is the default campaign setting for GURPS Fourth Edition. In the near future, the technology to jump between parallel worlds, parachronic travel, is developed and available to those who can pay the licensing. While some groups explore the worlds of the quantum strata, others struggle against Centrum, a parallel world government that wants to unify all the multiverse under their aegis.
