Sid Meier's Alpha Centauri™ Planetary Pack (1999)

About This Game

Sid Meier’s Alpha Centauri™ Planetary Pack includes the original Alpha Centauri and the expansion, Alien Crossfire.

Mankind begins its most monumental task – the colonization of space. A crew of internationally renowned scientists and security strategists, with wide-ranging convictions and diverse ethics, embarks on a mission that will change the world.
One Planet. Seven unique factions. Which will you lead?
Each faction has its own agenda, each leader a final goal. You must play to each strength and exploit each hidden weakness in your quest to rule the future.


The story unfolds via the introduction video, explanations of new technologies, videos obtained for completing secret projects, interludes, and cut-scenes. The native life consists primarily of simple wormlike alien parasites and a type of red fungus that spreads rapidly via spores. The fungus is difficult to traverse, provides invisibility for the enemy, provides few resources, and spawns “mindworms” that attack population centres and military units by neurally parasitising them. Mindworms can eventually be captured and bred in captivity and used as terroristic bioweapons, and the player eventually discovers that the fungus and mindworms can think collectively.


  • Great spin-off of the legendary Civilization series, in a refreshing Sci-Fi setting
  • Design your own units. Balance their speed, power, and toughness to suit your current tactical needs
  • Seven factions to chose from, each with its own artificial intelligence model that creates a very suggestive feeling that you are up against real people
