Xonotic places focus on community involvement as its principal driving force and structures itself to respect that. The aim of Xonotic is to become the best possible open-source FPS (first-person-shooter) of its kind.”
About: The last release of Nexuiz (2.5.2) was on the first of October 2009, and when we decided to fork early March 2010 we continued where we had left off with Nexuiz. Large parts of the code, graphics and music have been redone and have improved immensely. In over a year we have managed to make huge progress on pretty much every part of the game. However this release is still a preview, which means that bugs are likely to exist and that some of our decisions turn out to have unwanted side effects. This first preview also still has a limited number of maps, but we do have many maps being worked on for future releases! In the next sections we will explain what new features are available and the main things that have changed from Nexuiz.
This capture is from the built in demo. Looks like a fun project and well worth a play. Below; you can find a how-to on the game mechanics.
