After I reviewed Alien Arena last year, some readers criticized my choice of that first-person shooter (FPS) as the best free software game I had played. Several suggested Nexuiz would have been a better choice. At the time, I had not played it. Now that I have tried Nexuiz 2.4, it has become my favorite free software FPS.
Nexuiz runs on an improved Quake engine called DarkPlaces. The engine has been undergoing on-and-off development by Lord Havoc, the game's creator, for several years. On icculus.org, Lord Havoc says he developed a custom OpenGL-only engine for DarkPlaces, and other modifications that "support Windows WGL and Linux GLX and have greatly improved graphics and image quality."
