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.
Use the CONQUER button on the Base Control Screen to build up your military. In this mode your base will produce military units of all varieties, and their associated facilities, such as Command Centers. Use this button whenever you need to attack or defend.
