Amid Evil The Black Labyrinth is the grand conclusion to one of the best throwback FPS games on Steam. The "expansion pack style DLC" for Amid Evil casts you back to the old-school days of Quake, Doom, and Hexen in a prequel to the base game that sees you attempting to reclaim the Axe of the Black Labyrinth.
