It's the year 2112. Earth has been invaded by the forces of evil. Battle with the invaders as you race from sector to sector on your motorcycle searching for survivors. Feel the incredible sense of speed as you zip past evil Quadrunners and zigzag between treacherous rocks, oil spills, and other obstacles on the course. For a different challenge, create your own course in Design Mode using the various twists, turns, and straight-aways the game has to offer. Remember, you are Earth's only hope--you are Mach Rider!
