Alien Arena 2007 is a free/open-source first-person shooter game based on source code released by id Software. Started by COR Entertainment in 2004, the game combines a 1950s-era sci-fi atmosphere with gameplay similar to the Quake, Doom, and Unreal Tournament series. Alien Arena is primarily an online multiplayer action game, although single player campaigns are also available against bots.
Alien Arena is multi-platform and playable on Microsoft Windows, Linux and FreeBSD. Ubuntu users can simply download and install the game using Synaptic Package Manager.
