Developed by the Broken Glass Studios mod team, this is the version 1.0 beta of The Dark Mod for Doom 3.
"The Dark MOD is a total conversion for Doom 3, turning it into a dark and moody stealth game inspired by the Thief series by Looking Glass Studios. We have created a toolset with revamped gameplay, AI, graphics, HUD and weapons to allow fans to create missions in a gothic steampunk universe."
