Every stage ends with a rocket preparing to launch, and your job is to reach it in time to stop it. Standing between you and that goal is a gauntlet of escalating hazards—tacks embedded in the ground, barrels rolling in from behind, enormous ice stalactites crashing down from above, dust tornadoes, and unpredictable lightning strikes. Dirty Joe may show up on a skidoo specifically to chase you down. Moving platforms add to the chaos throughout. Speed is everything; hesitation is not an option.
