Doom, the Roguelike

Doom: The Roguelike, or DoomRL, is a roguelike game by Kornel Kisielewicz, based on the Doom universe. Like any typical roguelike game, it takes place in a randomly generated dungeon represented with text-mode graphics. All of the enemies, weapons, and items are from Doom or strongly Doom influenced, although the author has taken a few liberties to adapt them to this style of game.
