The Classic Doom 3 modification is a remake of the original 1993 Doom game, by id Software, in Doom 3. The main emphesis is that of brining the older game up to date in a modern graphics engine. The project makes use of all of Doom 3's advanced graphical features while retaining the atmosphere of the original game. This mod only works with the original retail release of Doom 3, patched to version 1.3.1. This mod does not currently work with the Doom 3 BFG Edition. Some BFG source ports are available that reportedly work with this mod, but are untested. The project is complete, and only includes the shareware levels.
Classic Doom 3 brings back the old joyous memories of Doom 1 Episode 1. Whats not to love of replaying old maps with upgraded graphics and music.
