Command Center

Often called CC for short, this is the main building in the game. All other Building's Levels are limited to the same level as the CC, or lower, and therefore all progress is limited by CC level. In March 2013 new Buildings were introduced which had other Buildings besides the CC limit their construction Level; one example is the Constructor which is limited by the CC Level and the Defense Lab's Level.

Click on the CC and its Build key or the Build key on the right HUD to bring up a list of buildings that can be installed on its Base. Base size is increased at L13, L14, L16, and L17 CC.

If your CC is destroyed in combat, you lose the battle, so be sure to surround it in a cluster of turrets and buildings. The CC is not always the target of troops; most troops target the sniper turrets first. When you destroy a CC, you win the battle even if you had not attacked the other Buildings. So, the best strategy for winning a battle is to target the CC and get as near as possible, so you can bring in Battle Cruisers, Blast Bots, Bombas, Decimators, Pulse Tank, Specters, or Devastators to finish it off. General Strom's Plasma Cannon and General Thrax's Focus Fire and Energy Beam can bypass other buildings altogether and win a battle in seconds. This is an extremely good way to defeat a base, although it does require a General's Orders.
