Nexuiz is a free open-source first person shooter that runs on Windows, Linux and OSX. Nexuiz is a 3d FPS deathmatch game project, Nexuiz is based on the Darkplaces engine. The darkplaces engine is an advanced Quake1 engine developed mainly by Forest "LordHavoc" Hale, who has been working with the Quake1 engine for many years.
A few of Darkplaces main features are Quake3bsp support, realtime lighting and shadowing, new particle effects, advanced menu system, and Md3/Md2 model support. Because Nexuiz is based on the Quake1 engine, its source code along with its content is entirely GPL.
Nexuiz focuses on bringing the FPS back to the basics with quick, lethal battles and balanced weaponry. As of the current release there are 9 weapons and 24 official maps, as well as 15 player models, with an average of 2 skins each.
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, if not all, Quake modifications (although with varying functionality). Currently there are a few custom mods and maps used.
Nexuiz is a fast paced 3d deathmatch game project created online by a team of developers called Alientrap. It is available for download for Windows, Mac, and Linux (all the same archive).
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 2.4 and new releases being developed.

Nexuiz is a 3d deathmatch game that has been in development since the summer of 2002. The goal of the project is to create a high quality first person shooter that can be played freely across all platforms in one package: PC, Mac, and can be even included in Linux distributions. The game is entirely open source, with the sources of the engine, gamecode, map files, and compiling tools, all included with the download, all under the GPL license.
The gameplay is deathmatch with the most excessive possible speeds and weapons, giving incredibly intense fast paced action. Along with deathmatch, there are multiple gamemodes such as team deathmatch, capture the flag, domination, and many mutators and weapon options like rocket arena and instagib. The user can fight through the single player campaign, going through over 20 levels, or play online with our server browser.
