Feel the rush as your kart rockets across the ceiling. Race upside-down and along walls on anti-gravity tracks in the most action-fueled Mario Kart game yet. Take on racers across the globe and share videos of your greatest moments via Mario Kart TV.

Driving up a waterfall or across the ceiling can provide an intense adrenaline rush, but that's not all anti-gravity is good for. It also provides a wild new gameplay mechanic: if you collide into other racers in zero-g, you'll earn speed boosts worth bragging about. Upload and share your best moments and watch your friends' using Mario Kart TV. Returning features include 12-player online play, gliders, underwater racing, motorbikes, and custom karts. You can even race as Bowser's seven minions, the Koopalings.
