The demo of the fifth installment of the Burnout series, Burnout Paradise, has hit Xbox Live as a free download for Xbox Live subscribers. Rumor has it there are some goodies within the demo. There are billboards scattered throughout the demo level that can be smashed through and will be counted. Rumor has it that there is a drivable Bumblebee rewarded for smashing through all of the billboards—nah, I'm just shitting you. I have no idea if there is a reward for smashing the billboards, but that would be sweet, right? [Kotaku]
