Super Mario Bros. U is a new, side-scrolling adventure featuring Mario, Luigi, Toad ... and your Mii character! Now's your chance to step inside the Mushroom Kingdom and explore new worlds, new power-ups and new ways to play. Swoop through levels and cling to walls when Mario transforms into Flying Squirrel Mario, or gently float through the air while hanging onto Tiny Balloon Yoshi.
Boost mode also makes cooperative speed runs possible for the first time. Use the GamePad to interact with and manipulate enemies and objects in real time, allowing for new ways to find the fastest routes through each level.
