The Power Plant being the most important buildings seconded by the Command Center . These feeble looking buildings are the powerhouse of your base, wreck them out and you shut down the base defence towers.

A base can have a minimum of 1 and a maximum of 4 power plants. They are the buildings you should look out for to take down first. These buildings have a unique feature; they have an option to "Overdrive". That simply means the plant overdrived will make 50% more energy and suffice your energy needs for upto 4hrs. Beyond that they self destruct and u have to repair them from scratch(This is dangerous if you are vulnarable to get attacked).
