New Super Mario Bros. U

New Super Mario Bros. U is an upcoming side-scrolling 2.5D platform game for the Wii U. It will be the fourteenth title in the main Super Mario series and the ninth installment in the Super Mario Bros. series. It is based off the New Super Mario Bros. Mii tech demo shown at E3 2011. The game was fully revealed by Reggie Fils-Aime at E3 2012. The game uses new, more detailed background styles, many of them resembling paintings, and its theme is most likely flying squirrels. The game introduces the Flying Squirrel power-up, acquired by Mario and his friends by an acorn-shaped Mushroom called the Super Acorn.

Gameplay Features
The gameplay of New Super Mario Bros. U is very similar to that of the New Super Mario Bros. games, mostly similar to New Super Mario Bros. Wii. It features new power-ups such as the flying squirrel suits and the option to play as the player's Mii. It also features a cooperative multiplayer mode, much similar to its prequel. Baby Yoshis from Super Mario World are included in the game, each with different abilities similar to Yoshi's power-up abilities in Super Mario Galaxy 2 (The blue Baby Yoshis can blow bubbles, the magenta ones can balloon up and the yellow ones can glow). A fifth player can also join in using the Wii U GamePad to assist the other players by putting in blocks, in a mode known as Boost Mode. There will also be a new mode called Boost Rush where Mario takes on a Speedrun-like speed. The map will styled similar to Super Mario World.
