A new patch is now available for UFO: Alien Invasion, updating the freeware UFO strategy game to version 2.3. Word is: "The UFO:AI development team is proud to announce the release of UFO: Alien Invasion Version 2.3. Two years in the making, this version features loads of new content, a dramatically improved rendering engine and extensive improvements to nearly every aspect of the game's campaign and battle systems." Thanks Derek.
