Mutant: Year Zero is a post-apocalyptic role-playing game, published by Modiphius Entertainment and developed by the Swedish games studio Free League Publishing, under license from Paradox Entertainment.

Mutant: Year Zero goes back to the origins of the Mutant franchise: role-playing after the Apocalypse. In this game, you play as one of The People - heavily mutated humans living in The Ark, a small and isolated settlement in a sea of chaos. The outside world is unknown to you, and so is your origin.
