New Super Mario Bros. U is the newest Mario platform game and launch title for the Wii U.


Deciding to take a break from his usual plans, Bowser and the Koopalings invade Princess Peach's castle and use a giant mechanical arm to throw Mario, Luigi, and two Toads away into the distance. Mario and his friends must now traverse across a new land to get to Princess Peach's castle and save her from Bowser. Along the way, they encounter the Koopalings and a few other more minor enemies, and eventually reach Peach's castle. Bowser has transformed it into an evil reflection of himself during the absence of Mario and company. After a long battle, Bowser is defeated, and the castle returns to its original state. As Mario and company celebrate the victory, Bowser and his forces are forced to flee.


New Super Mario Bros. U started development shortly after the release of New Super Mario Bros. Wii and took three years to develop.

The game, initially entitled New Super Mario Bros. Mii, was first revealed at E3 2011 as one of several tech demos demonstrating the capabilities of the Wii U. The demo's visual style duplicated New Super Mario Bros. Wii, but featured high-definition graphics, and Mii characters were notably featured as playable characters alongside Mario and Luigi. Shigeru Miyamoto later announced that the Mario demo was going to be released as a full game for the system, and would be demonstrated in its revised form at E3 2012. The new game, titled New Super Mario Bros. U, was revealed at the event and was announced to be released alongside the Wii U console.

The game's soundtrack was written by composers Shiho Fujii and Mahito Yokota, who each previously worked on New Super Mario Bros. Wii and Super Mario Galaxy. Koji Kondo served as the sound advisor.
