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, as well as the first 2D platformer since Super Mario World, to be released as a launch title for a Nintendo video game console. The game uses new, more detailed background styles. The game introduces the Flying Squirrel power-up, acquired by Mario and his friends by an mushroom-like acorn called the Super Acorn.

Story
Mario, Luigi, Blue Toad and Yellow Toad are in Princess Peach's Castle having some sweets 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.

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 Super Mario World, with similar features and designs, and New Super Mario Bros. Wii, with the return of the 4-player multiplayer. Though this time, players can play as their Miis, including the first player, who can also choose whoever to play as. A fifth player can join as well, though he/she will use the Wii U GamePad to assist the players, in a mode known as Boost Mode. This mode allows the fifth player to create temporarily blocks to either assist or annoy the other players, simply by touching the GamePad screen. The player operating Boost Mode can also stun enemies.

Power-ups, like the Fire Flower, Ice Flower, Penguin Suit and the Mini Mushroom, are returning. The game also features a new power-up, the Super Acorn, which gives Mario and co a Flying Squirrel Suit, which lets them glide and grab on to walls.

World Map Sections
Unlike previous New Super Mario Bros. titles, where the worlds were separated like in Super Mario Bros. 3, New Super Mario Bros. U has a seamless world map, similar to Super Mario World. Though, like the previous games, there are Fortresses, Castles and the occasional Ghost House within each part of the world, as well as different themes for each section of the map:


 * Acorn Plains: A grassland setting with lots of shrubs, slanted mountains, like in Super Mario World, and the game's main feature, the Acorn Tree.
 * Layer Cake Desert: A desert world with various desserts, such as melting ice creams, giant cakes, and a sea of sand with Moai statues.
 * Frosted Glacier: A snowy world that takes place at night filled with constellations.
 * Sparkling Waters: A tropical world with multiple islands and bubbling water geysers.
 * Soda Jungle: A rainforest-esque world similar to the Forest of Illusion, with giant enemies and blocks, similar to Big Island.
 * A mountainous world with tall, pillar like mountains.
 * World 1 from the previous New Super Mario Bros. games: A grassland world containing mushroom hills and Peach's Castle. It has been taken over by the Koopa Troop and is surrounded by a tornado.

Yoshis
Green Yoshis make a return, acting much the same as in New Super Mario Bros Wii. Baby Yoshis also return, which haven't been seen in a Mario platformer since their Super Mario World debut. Green is the only color available for Yoshis that the players ride on, unlike New Super Mario Bros. Wii.

Baby Yoshis

 * Bubble Baby Yoshi: Blue Baby Yoshis that release bubbles from their mouths. Enemies caught in these bubbles will turn into 3 Coins. They appear on the Frosted Glacier map area.
 * Balloon Baby Yoshi: Magneta Baby Yoshis that expand like a balloon and gently float in the air. These Baby Yoshis are similar to the Blimp Yoshi power-up, found in Super Mario Galaxy 2. They appear on the Acorn Plains map area.
 * Bulb Baby Yoshi: Yellow Baby Yoshis that light up dark areas and can stun emenies. These Baby Yoshis act similar to the Glow Blocks, found in New Super Mario Bros. Wii, and also Bulb Yoshi from Super Mario Galaxy 2.

Options
As well as the main adventure, their are other options to choose from. There is Challenge Mode, where players have to complete a objective, with some having a time limit. Another mode is Boost Rush Mode, where players have to reach the end of two to three selected stages, much like the Coin Rush feature in New Super Mario Bros. 2. Unlike Coin Rush, the stages are auto-scrolling, meaning the player has to keep up with the stage, which speeds up every time the player collects coins. Coin Battle from New Super Mario Bros. Wii will be returning.
