DoomRL

DoomRL is a roguelike game for Microsoft Windows, Linux and FreeBSD, and is a fan-created work set in the Doom universe. It borrows many of the monsters and game elements from Doom and Doom II.

Because it has the Doom weapons, DoomRL emphasises ranged combat. In many other roguelike games, melee combat is essential, at least in the beginning of the game before the hero learns other techniques. In DoomRL, the hero can immediately start shooting. Melee combat is only strictly necessary when the hero lacks ammunition, and that tends to happen only in the early game. Most enemy monsters also have guns.
