From C64CG website, "Joystick in port 2, forward to accelerate, left/right to steer, and down to break. Holding fire and pushing left/right will punch in that direction. When you are totalled, or somebody wins the race, you need to reload the game to play again :-D

You are racing through the desert, the police are about, and have set up some blockades. You need to out-speed, out-wit the morons you are racing, while staying on your bike."
