Modifications for dhewm3

Unfortunately dhewm3 can’t support all old Doom3 modifications, as it’s incompatible with old Game DLLs. This means that old Mods are only supported if they either have been ported to dhewm3 or don’t require their own Game DLL (but are using the one from the main game).
The essential requirement for porting Mods to dhewm3 is that the original Mod authors must release the source code under the GPLv3 license (that id Software chose when open sourcing Doom3). The dhewm3 SDK project page has more information.
General information about idTech4 (Doom3, Quake4, Prey, ET:QW, …) modding can be found at the idTech4 ModWiki.

NOTE that all mods (except for Fitz Packerton, which is a standalone game) require the full version of Doom3 (some also need the Resurrection of Evil addon, see the mod descriptions below for details).

General Mod Installation instructions

Mods generally consist of two parts:

1. Their game data, which is generally in a directory named after the mod, like dentonmod/.
   That data usually is mostly .pk4 files, but other “loose” files in the mod directory may also be used.
   • It must be put in an appropriate location, just like the game data from the base game. There the mod directory (e.g. dentonmod/) must be next to the base/ directory (that contains the game data of the main game).
   • See the list of Mods below for where to get the game data.
2. Their mod .dll, built from their gamecode, which must’ve been be adjusted for dhewm3 and must have the same name as the mod directory, but with .dll (or .so or .dylib, depending on your operating system) at the end, like dentonmod.dll.
   • Not all mods need their own .dll though, some use the base game’s gamecode and just have their own game data.
     If a Mod is listed below and mentions a .dll, it needs one.
     That list also mentions where to download the prebuilt DLL for x86 Windows (or .so libs for x86_64 Linux), usually they’re provided with the latest dhewm3 release, in the dhewm3-mods-* archives, and where to get the sourcecode to build it yourself.
   • The Mod .dll (e.g. dentonmod.dll) must be next to base.dll, generally next to dhewm3.exe - NOT in the mod directory!

Things to keep in mind if you’re not using Windows

• In the instructions above, mentally replace .dll with .so or .dylib or whatever dynamic libraries are called on your operating system, and replace dhewm3.exe with dhewm3 or however the dhewm3 executable is called on your system
• Note that Doom3 requires mod names to be lowercase, so both the mod directory and the dll must only have lowercase characters (like dentonmod/ instead of Dentonmod/). On Windows it happens to work even if this rule is not followed, because its file system is case-insensitive. On other operating systems it might not, so you may have to rename the mod directory accordingly. This is also mentioned in the mod-specific instructions below where needed
• Currently dhewm3 only provides prebuilt mod libraries (.dll/.so) for x86 Windows and x86_64/amd64 Linux. If you’re using a different operating system (or CPU architecture) you’ll have to build the “Mod .dll” yourself. The list of mods below links the mods source code and you can find generic build instructions at the dhewm3-sdk project page
