Sid Meier's Alpha Centauri, FIRAXIS' second title, was released in February 1999. This epic science fiction turn-based strategy game takes Sid's legendary gameplay into the 22nd century, offering the perfect balance of exploration, discovery, empire building and conquest. Since its release, Alpha Centauri has become one of the best-selling games around the world. In September 1999, FIRAXIS further enhanced the Alpha Centauri experience with the release of Sid Meier's Alien Crossfire, nominated for 1999 "Expansion Pack of the Year".

Explore the alien planet that is your new home and uncover its myriad mysteries. Discover over 75 extraordinary technologies. Build over 60 base upgrades and large-scale secret projects for your empire. Conquer your enemies with a war machine that you design, using over 32,000 possible units.

Sid Meier's Alien Crossfire Expansion Pack: Double the gameplay of Sid Meier's Alpha Centauri in the Official Expansion Pack, Sid Meier's Alien Crossfire. With seven new playable factions, a host of new gameplay additions, and a custom faction editor, this is a must have add-on for every Alpha Centauri fan.

Sid Meier's Alpha Centauri for Macintosh: Sid Meier's classic game of alien exploration and conquest is now available for the Macintosh.
