Absolute HD Mod - full compilation of best graphic mods for Doom 3.

10/10 - Agree Disagree

An Absolute MUST for Doom 3 fans: This mod improves and rejuvenates the life of Doom 3, whilst still showing appreciation to the old Doom 3.
Adding simple stuff, like a health and Adrenaline inventory, object manipulation (able to pick up objects), monster infighting, deadlier and brutal enemy AI, and Visual options out the whazoo, Absolute HD is an Absolute must have.

Although I do dislike the idea of longer weapon reload times, the fact you can't sprint & shoot, and the fact that so many people are reporting crashes and bugs may give you a wobbly start, but just re-installing it seemed to fix everything.

This mod is also compatible with the Steam version of Doom 3, and just install this into your steamapps & you're good to go, when you find it in the "mods" section of the game.
The Resurrection of Evil does not work with this mod, so there is a different mod to suit that need.
