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.
For me this mod isn't just a large scale, thorough TC, not only a fair tribute too.
Entirely, it is the reason, that urged me to acquaint with exciting Thief series and have extended experience on one of my favorite game's engine afterwards.
