- Use up and down arrows to control your paddle, and the left arrow to use a weapon. For a second player, the W and S keys control up and down, and D launches a weapon. - The red bars at the top show your health. - Hit the green targets on the sides to get a weapon, which will be displayed at the bottom of the screen until you use it. You can only hold one weapon at a time. - You cannot use another weapon until your last weapon has finished its destruction. (Otherwise there are too many weapons blowing up the screen at once.)
