This overhead view game kind of reminds me of Spy Hunter. Your overall mission is to take out as many cars and trucks as possible by knocking them into the walls. Be sure to clear the path for emergency vehicles otherwise you may suffer some consequences. Drive over the wrenches and nitro containers to pick them up, they will help you on your journey. Beware of the Taxi Drivers - those people are nuts. Use your mouse button to activate the nitro.
