Nexuiz is a free first-person shooter video game developed and published by Alientrap. The game was released under the GNU General Public License (GPL) and uses the DarkPlaces engine, a modified Quake engine. A remake, also called Nexuiz, has been released for Steam and Xbox 360 using CryEngine 3. The original game was released on May 31, 2005. Gameplay 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 supports new gametypes, or whole conversions quickly applied to it (much like Quake). Development Nexuiz development started as a Quake modification in the summer of 2001 by Lee Vermeulen. Soon afterward the project moved to the DarkPlaces engine created by Ashley Hale, who later also joined the project. The original design called for a simple deathmatch project with a few levels and one character model to be released the next summer. After four years of development with no budget, Nexuiz 1.0 was released on May 31, 2005, completely under the GNU GPL, and by the end of June had over a quarter million downloads. Development continued after the initial release, with 1.1 released soon after, 1.5 released February 14, 2006, 2.0 released June 14, 2006, and 2.1 September 9, 2006. On February 29, 2008, nearly three years after the initial release, version 2.4 was released and brought major improvements to both the GUI and the graphics engine. This includes all new GUI graphics elements, as well as reflective water and improved particles. In October 2008, a call was made for more developers for Nexuiz by the main (and only) QuakeC developer, who identified organizational issues associated with many users. Responses to this call highlighted the need for better documentation of QuakeC and the Nexuiz code, while also acknowledging the difficulty that documentation of this placed on the small team of Nexuiz developers. From mid-November 2008, a number of people expressed interest in continuing development of Nexuiz. On March 1, 2010, it was revealed that IllFonic purchased the rights to the name Nexuiz. On March 22, 2010, the fork Xonotic of Nexuiz was announced. Many of the core contributors and community members of Nexuiz moved to this new project as they felt that sale of the name Nexuiz mishandles the original project. On July 13, 2010, Crytek
