Meet REV by WowWee: a smart car that you can control from your smartphone. These cars are smart, so they can think, drive, or fight on their own. They are equipped with Beacon Sense technology and do not require a special surface to run on. You can use 16 cars in each game. Each AI opponent has a different set of skills, weapons, and moves.
REV lets you take on human or AI opponents to kill time and unlock weapons and special moves. These cars are smart enough to know where they are in relation to each other. Sets you back under $100 at this time.
