Namco Bandai will launch Mario Kart Arcade GP DX this summer.
So far all the company's shown of the third Mario Kart arcade game is a handful of screenshots, but these at least reveal that gliding and underwater driving (as featured inMario Kart 7 on 3DS) will feature.As well as the Grand Prix and four-player race modes offered in the previous arcade releases, it will feature a new "Alter-Ego" mode which uses ghost racers retrieved online.
It's been confirmed that Don-chan, the main character from Namco's popular drum-based rhythm action game Taiko no Tatsujin, will be a playable character. There will also be a new track based on the Taiko no Tatsujin world.
This is nothing new for a Mario Kart Arcade GP game - previous entries in the series have also featured Namco Bandai characters, including Pac Man and Mametchi from Tamagotchi.
