Previous chapter → Constructions
Many buildings can be upgraded after they are constructed. This leads to a greater complexity. Additional elements such as workers are required for everything to continue to run smoothly. At the same time, each level increases production, often combined with further improvements. You can find out which these are in the area → buildings.
To upgrade a building, all you have to do is click on the upgrade icon inside the building (see → Building UI). In the → Upgrade UI that then opens, the changes and the necessary product quantities are displayed. These are taken from the → control center when the expansion order is placed.
