A collection of 15+ years worth of fan-made improvements to the game we love in one big easy to install package. Just buy the game (http://www.gog.com/game/sid_meiers_alpha_centauri), download (download as zip, mid right of this page), and unzip into your installation folder overwriting all duplicate files.

Got Alteria Centauri, but there's a few more. At least recent GOTMs, and Darsnan's got a few more hanging around.
