Instructions
Beat all Burning Route courses. Each car has its own Burning Route course featuring a race from point A to point B, and you will unlock many of the cars by simply progressing through the game and tallying up your wins. Beating a Burning Route course unlocks an upgraded version of your vehicle.
"Shut down," or destroy, all artificial intellence (AI)-controlled special cars in Freeburn mode. When you see new cars enter the world, you need to shut them down to unlock them. To shut down a car, you must perform one of the many "takedown" methods, including Wall Takedown, Revenge Takedown and Traffic Takedown.
Upgrade your license. You begin the game with a Learner's Permit and, as you complete events, gradually progress toward the Burnout License. Upon receiving each new license, a car will unlock and all events reset themselves.
Enter unlock codes. In the pause menu, access the Sponsor Product Code feature. You can unlock four different cars this way, but you must have an A Class License or a Burnout License to access them. The codes are as follows:
For the Circuit City Hot Rod, enter the code "circuitcity." Enter the code "bestbuy" for the Best Buy Oval Champ. To get the Game Stop Sport, use the code "gamestop." And to unlock the Wal-Mart WTR, enter the code "walmart."
