From the back of the book:
SURVIVE THE PARADOX
In 1943, the Ministry of Culture and Science of The Enlightened Confederacy ordered an experiment to test the theory of Space-Time Flows, developed by Möbius-Higgs. However, something went wrong: the explosion of one of the laboratory's particle accelerators caused the opening of the Breach, a portal between our world and the other infinite dimensions.
The Breach is a brutally fast-paced sci-fi horror RPG set in a dystopian retrofuture.
Inspired by the great sci-fi novels of the 70s, The Breach will catapult you through time and space to discover countless parallel worlds, the Paradoxes. As Watchers, you will be called upon to gather data and information in order to uncover the secrets of the Paradoxes, possibly returning to the Citadel safely.
