Complete the race challenge and defeat other cars until they demolish your vehicle. There is a certain amount of cars to destroy, so get patience and try to hit them first.
Have you ever seen car wars or anything, that will remind you about it? There is no place for weak drivers on the battlefield like that, but you are not afraid of danger. Get in your can and start the mission on eliminating other drivers and their cars. Destroy every single car on the level, without losing yours and collect bonuses to restore your health.
