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, the ninth installment in the Super Mario Bros. series, and the fourth installment in the New Super Mario Bros. series. It is based off the New Super Mario Bros. Mii tech demo shown at E3 2011. It will be the first Mario platformer game since Super Mario 64, to be release as a launch title for the home console. 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.

Story
Mario, Luigi, Blue Toad and Yellow Toad are in Princess Peach's Castle having lunch together. Bowser suddenly arrives in his Airship, now with a giant mechanical fist, that smashes and launches the brothers and the Toads towards the Acorn Plains. Mario and his friends crash into the Acorn Tree, launching Super Acorns through the area. Bowser then takes over Princess Peach's Castle again, setting the Mario Bros. and the Toads to go on a new adventure and save Princess Peach once more.

Gameplay Features
The gameplay of New Super Mario Bros. U is very similar to that of past 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 similar to its prequel. Unlike in New Super Mario Bros. Wii, the first player is given the choice of what character he or she wants to play as (in New Super Mario Bros. Wii, the first player has to play as Mario). 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. The player who is in Boost Mode can even help Bowser. There will also be a new mode called Boost Rush where any given level is transformed into an auto-scrolling level, speeding up and allowing the player a faster time as the player grabs coins, but also becoming more challenging. Another mode the Challange mode, allows players to collect as much extra lives as possible by jump on enemies repeatedly. The map is styled similar to Super Mario World, with all of the worlds connected directly to each other, rather than being separated as in previous New Super Mario Bros. titles.

Trivia

 * When the player's character is not moving, the character looks at the screen.
 * If the Miis are selected as P1, they will be colored like Mario. If P2, they will be colored like Luigi. If P3, they will be colored like Wario. If P4, they will be colored like Luigi's light-blue palette swap in the Super Smash Bros. series and Player 4 in the remakes of Mario Bros..
 * New Super Mario Bros. U is heavily influnced by Super Mario World to the point where they are both launch titles for their respective consoles (Super Mario World was a SNES launch title and New Super Mario Bros. U is a Wii U launch title).
