The Reaction Quake 3 Website has the release of beta 2.00 of this Quake III Arena modification. Here is the succinct description of what's on tap with the latest release: "Along with new maps, a new user-interface, new models, and other graphical updates, the long awaited addition of Teamplay and replicated Action Quake 2 physics is included." The download is about 150 MB, and a previous version of the mod is not required.
