A game heavily influenced by William S. Burroughs, Phillip K. Dick, Robert Anton Wilson, Grant Morrison, experimental art and cinema and weird pop culture. Over the Edge is billed as a "game of surreal danger, secrets and conspiracies." It is set on a mysterious island in the Mediterranean, the nation of Al Amarja which, like Burroughs' Interzone, is a place where normal humans, real humans, mutants, parasitic extraterrestials, psychics, clones, voudoun houngans, decadent aristocrats, etc. interact. Various factions fight each other for reasons esoteric, political, racial, metaphysical, whimsical, religious, or all of the above, or for no reason at all.

The system is simple, emphasizing character ideas and story over mechanics. Characters are defined by Traits that they create, and the game mechanics are resolved with dice pools, using d6. The rulebook contains all the rules needed for play as well as the game setting, maps of Edge City and Al Amarja, details of the various factions, conspiracies, NPC's, businesses and organizations. The book is divided into Player and GM sections.
