You are the middle tank. Get the left and right tank by clicking the mouse with your mouse on an enemy, to try to shoot them. Use the arrow keys to move, rotate left, rotate right, go forwards, go backwards. If you can shoot both of them then you win, but be aware that you will not receive any win or lose messages, just that the game will end.
Based on griffpatch's tank multiplayer project. Thank griffpatch for the sprites.
