Xonotic 0.5 - Free Shooter Based Off Nexuiz

Xonotic is a free first-person shooter game for Linux, Windows and Mac OS X. The Xonotic project started as a fork of Nexuiz, a game which was popular for many years on Linux. The fork was created because Nexuiz was licensed to IllFonic game studios, and it is to be used as a platform for developing a commercial game for Steam, Xbox and PlayStation.
