From Alpha Centauri Wiki
Jump to: navigation, search

The technology tree in Alpha Centauri and its expansion is vast, with nearly 90 technologies shared across four categories (Conquer, Discover, Build, Explore). Depending on game settings, you can either direct research or randomly uncover technologies depending on your focus (default setting). The tree below attempts to chart the relationships between the different techs.
