THE DARK MOD was once a total conversion of Doom 3, and is now a STANDALONE GAME with the release of TDM 2.0! A dark and moody stealth game, inspired by the Thief series by Looking Glass Studios.

10/10 - Agree Disagree

Big fan of Thief series.
Love the atmosphere. Very interactive environment.
Some clipping issues on some maps,
but that might be the best mod I ever played.
