The d3_mod_database_1.2.zip file you have requested: Utilities / Doom3 Mod Manager - 1.64mb 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 version 1.2 of the mod manager utility that easily allowes you to install/uninstall mods from Doom3. New updates include:
Changes 1.2: Optimized download and update process, Code cleanup, Installer removed.
I still find it a little superfluous, because the game engine allows for easy install/uninstall, but that's just me.
