Mario Kart 8 is an upcoming kart-racing game in development for the Wii U. It is the eleventh installment in Nintendo's Mario Kart franchise, the eighth in the main series, and is due for release in May 2014.
It seems that it will take the glider and underwater mechanics as weel as the coins mechanic of its predeccesor Mario Kart 7. The bikes from Mario Kart Wii make a return though they have been changed to act similarly to Karts. 12 player races also make a return. In addition, the main new mechanic is an anti-gravity tranformation which will allow racers to drive along the ceiling and walls of courses allowing more different path as one races.
