Mario Kart 7
Mario Kart 7 is a kart racing game developed by Nintendo EAD in cooperation with Retro Studios and published by Nintendo. As with previous games in the Mario Kart series, players participate in racing on various Mario-themed tracks, playing as one of seventeen different Mario characters. While racing, the players make use of power-up items that either assist their character or hinder opposing characters. New additions to the game included hang-gliding attachments for karts, the ability to drive underwater, the ability to drive in first-person, and the ability to fully customize the vehicles' builds. Mario Kart 7 supports both local and online multiplayer for up to eight players and was released worldwide in December 2011. It was the second 3DS game to sell over five million units, following Super Mario 3D Land.
