Nexuiz was originally developed by Lee Vermeulen and Ashley Hale (Ladyhavoc), who started Alientrap in the summer of 2002. The goal of the project was to create a high quality first person shooter that could be played freely across all platforms in one package: PC, Mac, and Linux. The engine that powered Nexuiz was Forest Hale’s Darkplaces engine.

The first version of the game was released in 2005. Development continued with many online contributors over the years, with version 2.5 released in October of 2009. Since its release it has been downloaded over 6 million times, and is included with many Linux distributions.
