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.
THIS is the ultimate Doom 3 mod. The creators weren't just able to "port" the game into a new engine and graphics, but they were able to keep the feeling of the original Doom. The game feels modern yet very classic. I can't tell if the maps are 1 to 1 with the original game but you instantly get the impression as soon as you start playing. It makes you realize why the game was and still is one of the best of its genre. The developers did one hell of a job on this for sure !!! Too bad it ends with the very first episode: Knee deep in the dead. By the way there are cut scenes, intro and outro so they're not bothering you throughout the game. The cut scenes are made with a sense of humor, especially the outro. Download and play that thing !!! Ranks among my 5 favourite mods of all time.
