 Courses range from beaches with debris @-@ littered water to swamps and ice @-@ covered mountains . The game has its variant of the traditional race track , but also introduces a new course type known as a Suicide course . Instead of being a continuous loop , these tracks have checkpoints at either end of the course , and the starting grid in the center . Riders race to one end , then turn around to head for the other checkpoint , repeating the process until all laps are complete . This provides a new gameplay dynamic as often the player must navigate oncoming traffic .
