Command center

Your command center is the main building in your base and the center of all of your operations. Upgrading your command center has two benefits. First, it allows upgrading your resource buildings to higher levels. In general, you must have a command center of level X in order to upgrade a Warehouse, Foundry, Oil rig, Armory, or Ionite mine to level X; the Quarters also unlock higher levels with command center upgrades (although not the same level).

The second benefit is taxes. Each upgrade allows you to collect a new set of taxes every day. In order to get taxes, you must add friends on Kongregate who play the game, and then add them to the command center. Once they have been added, you can then collect taxes. At higher levels the taxes are extremely useful.
