This is a graphical overhaul for both Doom 3 and Resurrection of Evil, but minus any of the gameplay, monster speed/behavior, or first-person animation changes that are added in the newer "Absolute HD" versions, which I don't like. This mod incorporates lots of smaller graphical mods, but I don't know all of the details, see Description. I have heard that this mod works with both CD-ROM installations and with Steam but I've only used it with Steam, so if you have CD-ROM problems I probably can't help you. It is not compatible with BFG Edition. I don't claim any credit for creating this mod, It was done by Cverdzislav, I believe, but this older version has disappeared and I don't like his newer versions as much, plus if comments are to be believed they have some problems. Please contact him if you have any technical questions beyond basic installation/troubleshooting, as I don't know enough to be helpful.
This is the main mod installer file. Run this to install the mod, might be a good idea to run it as an Administrator.
Run and install to base Doom 3 directory. Make sure it doesn't install to another Doom 3 directory within the main Doom 3 directory, if it does, cut and paste so things are where they should be.
