Nintendo has announced Mario Kart 8. The game will be the franchises first foray into HD. A new antigravity feature will allow players to race on walls or upside down. Also new to this game will be 12-player online competitive play. Elements found in previous Mario Kart games such as hang gliders, underwater racing, motorbikes and mid-air tricks will make their return in this one. Waluigi and Toadette will rejoin the cast of characters. Mario Kart 8 is coming to the Wii U in Spring 2014.
