The player will travel through prisons, rifts, mazes, fortresses, forests, graveyards, sewers, factories, labs, the Hell, haunted libraries, all to chase down (or be chased down) by new stronger demons and bosses, but with the help of new powerful weapons at his disposal. The wad presents 3 new Episodes, with 14 new levels, 12 + 2 secret, a Hub (reachable by beating the final level or just by entering the "Reliquary" episode), from where you can play all of the levels pistol starting (actually "fist starting"), go to a "testing area", change the skill level and reach the secret 15th level, a wave based arena.
