In this game you fight the enemy using tanks and other military units. First, you build the unit you're going to use. It can be any unit that is unlocked and that you can afford. Once you build a unit, you move it on the battle field with the arrow keys and shoot with space. Your goal is to destroy all enemy units and destroy or capture all buildings. To capture a building, just place your unit over it and wait until the blue bar is filled. Some buildings are special. For example, capturing a harbor gives you reinforcement and capturing the airport drops power-ups.
