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.

What Doom III should have been.

This mod brings the original Doom to ID Tech 4. The visuals are not only impressive to look at while you're gunning down Cacodemons or chainsawing a group of demons, it gives you the impression of "Hey! THIS IS DOOM. DONT TAKE IT SERIOUSLY. NOW SAVE THE EARTH, YOU PANSY". Yes, the re-design is quirky but the lighting is where the treat really is.

The gameplay experience has a tough time replicating the difficulty of the Doom series but you can fix that by choosing a higher setting. Other than that, it is what it is. A conversion and it satisfied me even if the mod was really short.

In conclusion, while this mod replicates the Shareware version of Doom, you cannot pass up this gem of interest.
