The beta_mod.rar file you have requested: Modification / DooM Beta Mod - 2.27mb 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 mod is based on the beta version of Doom 3 PC and Xbox. I always wanted to make something similar to those 2003 trailers from Xbox & PC version.
