The Explore, Discover, Build, and Conquer buttons on the Base Control Screen activate the Governor for that base. When the Governor is activated, he will make decisions automatically based on his general instructions. This function is useful for beginners and for players who do not wish to micromanage their bases.
The BUILD button on the Base Control Screen mandates infrastructure and growth. The Base Governor will tend to build Facilities and Formers. Use this button at any time to have your base concentrate on peaceful growth.
