What is OpenArena?

OpenArena is a First Person Shooter that uses the ioQuake3 engine and builds an enhanced framework around it. The game, like its engine, is free and Open Source. It works with Windows, Linux, and Mac OS X.

Since ioQuake3 was developed from the “id Tech 3” engine, the game is almost the same as Quake III Arena but with many new benefits – http://ioquake3.org/improvements/
