In Car Mayhem, you have to race down a crowded highway while blowing up as many cars as you can. To make things more difficult for you, the road is littered with barriers. The barriers will stop any car that slams into them, which makes them sitting ducks for you to shoot and blow up -- but swerve out of the way on time or you'll crash into the wreckage and get blown up as well! Use the money you earn during your road rage rampage to purchase new weapons and upgrades for your car. The mechanic and the mad scientist will be happy to help you out in exchange for a little cash (or a lot of cash, depending on what car modifications you want). Every now and then you'll encounter a police barricade. Find the weak spot and barrel through!
