The Dark Mod is a Doom 3 total conversion which turns the game into a dark and moody stealth game inspired by the Thief series by Looking Glass Studios. Thief's Den is a short alpha demo of The Dark Mod which offers just a few rooms, but it is a complete, fully playable mission, and includes a good selection of the main Dark Mod features.
