Mario Kart 8

Mario Kart 8 is an upcoming Mario Kart game for the Wii U, releasing in Japan on May 29th, both North America and Europe on the 30th and the 31st for Australia. The game is the eighth installment in the mainstream series, and eleventh overall in the Mario Kart series. Anti-gravity, a new feature for the Mario Kart series, has been confirmed. Bikes, gliders, and underwater driving are also confirmed to return.

Gameplay
The gameplay maintains the traditional elements as most Mario Kart games, mostly from the two recent installments from the Wii and 3DS respectively. The karts, featuring a similar design to Mario Kart 7, maintain the hang-glider and underwater features from the previous game, while bikes make a return, albeit handling similar to the karts this time around, both can be customized with, according to an interview, more customization options. . Also, like Mario Kart Wii, twelve racers are present in normal races.

The newest feature for the series is anti-gravitional segments, that not only allow for more dynamic track design, but allow racers to drive across the side of a track and upside-down as well. These tracks have been described as more narrow when compared to previous Mario Kart tracks, specifically those from Mario Kart Wii. For the fourth time in the series, courses from previous Mario Kart games will be included, and both the game's anti-gravity mechanic, as well as Mario Kart 7 's "air, land & sea" mechanic will be incorporated into these retro courses, much like the retro courses in Mario Kart 7. An aesthetic change includes the kart headlights turning on in a dark area.

It has been confirmed that there will be Miiverse integration, which will allow players to share their replay videos and comment on others' videos, in a featured called "Mario Kart TV". When in anti-gravity, if a racer bumps into another racer the kart spins rather than just bumping and the racers receive a speed boost. Coins, introduced in Super Mario Kart and returning in Mario Kart: Super Circuit and Mario Kart 7, also return for this game, and like Mario Kart 7 the player can only collect up to ten coins at one time. Another change is that in 2-player mode, the screen will split down the middle vertically instead of the horizontal split used in the other console Mario Kart games, a feature that was originally intended to be in Mario Kart 64 but was removed from the final game.

Development
Development for Mario Kart 8 started in 2012. Some ideas that were scrapped in Mario Kart 8 included a drill that made drivers drive into subterranean depths. The idea was scrapped because the developers thought it was not as interesting as the anti-gravity idea. The anti-gravity concept stemmed from the Wii U being a powerful console, and with the upgraded hardware, the developers wanted to make courses with a 3D plane in mind rather than the 2D plane as the other tracks in the Mario Kart series.

The title, Mario Kart 8, is chosen to represent the anti-gravity mechanic as the "8" used in the official logo resembles the Möbius strip from Mario Circuit.
