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 was amazing

It's nice to be back on Phobos and play through the same levels as Doom: Knee-Deep in the Dead.

What I like about Classic Doom 3 is that some of the areas have been altered. Like when one or two elevators are now a latter, and that some of the boring looking areas from the classic are now enhanced with some style. And I also like the fact we can run without loosing our breath, and no reloading.

I do however have three disappointments

1. Lack of other items. No Computer map, but a backpack. And no Partial Invisibility, but at least there's a berserk. Above all no environment suits, and yet there's so many acid to walk on and it hurts.

2. No toggle map. I know Doom 3 wasn't made that way, but it would be nice to have a toggle map. Especially with Central Processing in that lava-like maze.

3. No progress with Episodes 2 & 3. I understand that Flaming Sheep Software is not interested in making those episodes. Still it would be nice to have a complete Classic Doom 3, just like Black Mesa. If there are any Deimos or hell related levels, I'm ready for them.

Still this mod is awesome, and I support total conversions.

Classic Doom 3 is one of my favorite mods now. 10/10

Happy Doomsday
