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.

I would simply fall in love with this mission by just looking this picture if I didn't know how bad it actually is.
