A new version 2.2 of the Q3F modification for Quake III Arena is now available (thanks Dan Hilliker). The new version offers 16 new or updated maps, gameplay adjustments, and a bunch of bug fixes. The new release is available for Windows, Linux, and the Mac as a patch, and work is underway on a full installer for Windows users. They also have a preliminary version of their work-in-progress Q3F guide.
