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. To test the latest Nexuiz, download the Zip archive from the official website (direct link here), uncompress it, and then run the binary specific to your OS (the archive includes binaries for Linux, as well as Windows and Mac).
Nexuiz - choosing the player model
Nexuiz 2.5 offers a futuristic interface, with fast access to settings and other configuration options. One of the nice things which bumped out when configuring the keys was that Nexuiz allows for switching between fullscreen and windowed mode just by pressing a key, even if the game is running. Older versions of Nexuiz used Shift+Esc in order to open the console, but it looks like in 2.5 you can use the classic ` key.
The server browser
Besides multiplayer, Nexuiz also includes support for bots and a singleplayer campaign. It comes with 15 player models, 13 weapons and 24 official maps, music and original character and weapon sounds.
Nexuiz will run smoothly on older machines at 1024x768, but you will need a decent video card to enjoy it on higher resolutions at a steady framerate. However, lowering texture details and particle details will help if you have an older video card and CPU.
Overall, I think Alientrap is doing a great job by continuously developing this game, which became one of the favourite FPS games for Linux users, together with other well-known names like OpenArena or Tremulous.
