Pump it up and Win

Your army is still weak. Enemies are advancing wave after wave. There is only one chance to survive: pumping, wit and cool head of the commander. You don't control every soldier - the battle goes on its own, and your task is to create an invincible fighting machine.
You'll start with a couple of fighters, but with each victory - the army will grow.
Enough said. The battles are waiting for you. The army is in your hands. Are you ready or are you too weak for this?
