This is a two-player game. To move the green tank, use the W, A, S, and D keys. To fire the green tank's gun, you press space. To move the blue tank, use the forward, left, right, and down arrow keys. To fire the Blue tank's gun, you press the 0 key. When The Boss's health drops to 0 or below, you (and your partner) have won!
