Nexuiz is one of the most popular shooter games which emerged after the open-sourcing of the Quake 3 engine, featuring a fast-paced game style and several game modes, like the popular DM or CTF. Nexuiz is a free, GPL-licensed, first-person shooter developed online by the Internet-based team Alientrap, and it comes with ports for Linux, Windows and Mac.
Ever since it was launched, in May 2005, Nexuiz went through a lot of changes and evolved with every release. The 2.5 series bring many improvements, featuring new graphics, new maps and an even faster gameplay. The latest version is 2.5.2, a bug-fix release to the stable 2.5 release.
