The Game
UFO: Alien Invasion is an open source strategy video game in which the player fights aliens that are trying to take control of the Earth. The game is heavily influenced by the X-COM series (mostly by UFO: Enemy Unknown). It is based on a modified id Tech 2 engine, and runs on Linux, Microsoft Windows, AmigaOS 4 [1], and Mac OS X for both PPC and Intel Macs.
UFO:AI has been nominated for "Best project for Gamers" in the Sourceforge 2007 and 2008 Community Choice Awards[2] and was positively noted by Linux Journal.[3]
