The d3_mod_database_setup.zip file you have requested: Utilities / Doom3 Mod manager - 2.54mb is not available. Perhaps try browsing all files for the game Doom III and upload any files you want to share or are missing. This is the only information we could locate:
This is a mod manger utility used for easily installing and uninstalling mods. I find it a little superfluous because the engine allows for easy install/uninstall by putting files in or taking out of a folder. To use this unzip and run the application.
