BackArrowGreen Back to Alpha Centauri

This is a list of all the technologies in Sid Meier's Alpha Centauri. Unlike the Civilization games, technology branches off into different paths; there is no absolute way to choose what appears. There are also no eras to advance through.

Industrial AutomationEdit

Easily one of the two or three most important technologies in the game. This technology allows you to build the Supply Crawler, a staple of virtually all advanced strategies, and additionally allows Wealth, which may be desirable, and the construction of Hab Complexes, which you'll need for bigger bases, and the Planetary Transit System, which is useful if you can spare the time and resources to grab it. On top of all that, you get more commerce. Getting this tech before anybody else does can easily swing the game in your favor even if you are otherwise behind in every other respect — but you must take full advantage of it.
