Mutant Future is a post-apocalyptic, science fantasy role-playing game created by Daniel Proctor and Ryan Denison and published by Goblinoid Games. The game is compatible with Labyrinth Lord, which emulates the rules of classic era Dungeons & Dragons (D&D) using the Open Game License (OGL) from Wizards of the Coast. The game is thematically patterned after genre predecessors such as Metamorphosis Alpha and its more widely known and published follow-up, Gamma World.
