Sid Meier's Alpha Centauri updated demo

By Electronic Arts Free to try

Developer's Description

Sid Meier's Alpha Centauri presents an epic science fiction struggle to gain control of an entire planet. Seven human factions, all with severe philosophical and cultural differences, vie for control over the new outpost of the human race--Alpha Centauri. Gameplay is turn-based, so there's plenty of time to ponder over each of your highly detailed moves. Building units can be customized, the direction of your society's research must be set, and the 3D terrain must be explored. The rich sci-fi storyline unifies the intricate and complex aspects of the game. Alpha Centauri is for those who want depth in their science fiction strategy games.

This updated version is based on what is speculated to be the final code for the release version of the game. It includes higher resolutions, gameplay fixes, and gamma correction. If you want to see the intro movie, download this 49MB version.
