Though a formal update is not expected on the Quake 3 Arena website until Monday morning, the source code for the Quake III Arena game .dll is now available on id Software's FTP site. Here is a local copy of the source (1.3 MB), along with the usual list of mirrors of this code essential to the construction of modifications for the game. A .plan update by Robert Duffy gives the scoop on what's up:

The game source is out. It should start appearing on mirrors soon. It is in idstuff\quake3\source and named "Q3AGameSource.exe"

There is a "How to make a mod" text file included which shows the very basics of building the source for debugging ( Win32, Visual C++ ) and building the vms for distributing mods. It also shows steps to get your mod to run with the engine.

PLEASE NOTE: The game source MUST BE INSTALLED in quake3 off of whatever drive you like. This is so the batch files and the lcc compiler can find all the right stuff for building vm's.

The tool source and video compressor will be out next week. This will include source q3data, q3map, q3asm, q3radiant, our version of lcc and the executable for the video compressor.
