 Issues, fixes and tweaks
- TweakGuides has created a comprehensive guide for fixing issues in this game. It can be found here.
It is possible to easily change many things in the game simply by modifying text files located in doom 3/base/pak000.pk4 (.pk4 files can be opened with WinRAR or similar programs). For example, to turn on plasma gun projectile shadows, go to "materials" folder, open "lights.mtr" (use WordPad or other text editor), search for "plasmaglow" and delete the "noshadows" line under it, then save the changes. Particularly the "def" folder contains definitions of monster health, gun damage, ammunition amount and lots of other tweakable game values.
 Linux Installation
To install Doom 3 on Linux create a doom3 directory and then copy the following retail pk4 files to your doom3/base directory:
If installing the expansion pack you must also copy the following retail pk4 to your doom3/d3xp directory:
After copying all pk4 files to your hard drive run the linux patch and direct it to your doom3 directory. You can start the game with the command: doom3. To launch the expansion use: doom3 +set fs_game d3xp
Do note that OSS has been disabled in later Ubuntu distros, and it is not likely that sound will work correctly (if at all).

 Open Source Engine
The source code to the engine was released under the GPL license in November 2011. There have since been several modifications. You can view the different branches and changes, as well as download them, from the github repository, if you are willing to compile the code yourself. The same group that worked on ioquake3 has said they will add features to the code and release compiled binaries under the title iodoom3. You will have to obtain the art assets separately.
Another available source port is dhewm3, which adds 64-bit support, EFX on all platforms, and other features.
