Nexuiz is a fast paced 3D deathmatch game project created online by a team of developers called Alientrap. The first version was released May 31st 2005, released entirely GPL and free over the net, a first for a project of its kind. Since then it has been downloaded over 1.5 million times, and the game is still being updated and developed, currently at version 2.5 and new releases being developed. Nexuiz is primarily multiplayer (though it includes a full single-player campaign, which allows one to play through the various multiplayer game types and maps with bots), and allows for hosting and joining of games. It can also support new gametypes, or whole conversions quickly applied to it (much like Quake). Nexuiz supports most Quake modifications (although with varying functionality). Currently there are a few custom mods and maps used.
