urban terror

I've been playing a LOT of UrbanTerror mostly because zog recommended it and it has AMD 64bit precompiled binaries available to play. This is a great game, the graphics arent so great, but as far as just get in there and start-shooting fix, its great. From the UrbanTerror site..

Urban Terror is a free multiplayer first person shooter, that does not require Quake III Arena. It is available for Windows, Linux and Macintosh. The current version is 4.1.
