In Armored War, you need to sit down and focus on your keyboard...set that mouse aside for a while. You won't need it. Here are the controls: use A to switch to your previous weapon, S to go for the next weapon, tap the space bar to activate the shield to protect you from attacks, hit the W button to make your tank go on steroids (turbo mode), and last BUT not the least, use the arrow keys (left, right, up, and down) to move your tank.
