This game requires one joystick plugged into the right-hand joystick port. The object of the game is for each player to make a safe landing on a landing site (the flat areas).
The more difficult the site, the higher you score. Point the joystick in the direction you want to fire the retro rockets. To fire the rockets, press Fire.
The amount of fuel you have remaining is indicated by a bar in the left-hand corner of the screen.
