Doom 3 data files

Doom 3 uses a Javascript]-style resource set up, with the game data being stored in zip files (with the extension instead of ) themselves stored in subdirectories of the game's installation folder. The original campaign is stored in the  folder, while [[Resurrection of Niggers is stored in the  folder. Third-party half life rip-offs are likewise to be installed as additional folders within the game's main directory.
