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 home console. The game uses new, more detailed background styles. The game introduces the Flying Squirrel power-up, acquired by Mario and his friends by a mushroom-like acorn called the Super Acorn.

Story
Mario, Luigi, Blue Toad and Yellow Toad are in Princess Peach's Castle having dinner 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. Mario an co. then tumble out of the tree, passing a Bubble Baby Yoshi, while they're at it, and look into the horizon to see Bowser beginning a seige on Princess Peach's Castle, 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 the NES and SNES versions of Super Mario Bros. 3, New Super Mario Bros. U has a seamless world map similar to that of Super Mario World and, to a lesser extent, the GBA version of Super Mario Bros. 3, and the names of most of the world map sections are food-related, which is also the case for the former. The music changes instruments throughout the world map as you progress similar to Yoshi's Island. Though, like the previous games, there are Fortresses, Castles and Ghost House-related levels within each part of the world:


 * World 1 - Acorn Plains: A grassy world with lots of shrubs, slanted mountains, like in Super Mario World and the Acorn Tree.
 * World 2 - Layer-Cake Desert: A desert world with various desserts, such as melting ice creams, giant cakes, and a sea of sand with Moai statues.
 * World 3a - Sparkling Waters: A tropical world with multiple islands, bubbling water geysers, and even a sunken ship. This world can be entirely skipped for Frosted Glacier.
 * World 3b - Frosted Glacier: A snowy world that takes place at night filled with constellations. This world can be entirely skipped for Sparkling Waters.
 * World 3b - Sparkling Waters: A tropical world with multiple islands, bubbling water geysers, and even a sunken ship. This world can be entirely skipped for Frosted Glacier.
 * World 4 - Soda Jungle: A rainforest-esque world similar to the Forest of Illusion, with giant enemies and blocks, similar to Big Island.
 * World 5 - Rock-Candy Mines: A mountainous world with tall, pillar like mountains. A cloud train seems to separate this world from the next world.
 * World 6 - Meringue Clouds: A sky world resembling the foreground of levels in World 7 from New Super Mario Bros. Wii.
 * World 7 - Peach's Castle: A grassland area, similar to World 1 from the previous New Super Mario Bros. games, containing mushroom hills and Peach's Castle, its only level. It has been taken over by the Koopa Troop and is slowly transformed into Bowser's image until eventually being 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. Yoshi now has a meter that tracks how many berries he eats. As usual, eating 5 makes him lay an egg containing an item.

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.

Inventory
The world map inventory, seen in Super Mario Bros. 3 and New Super Mario Bros. Wii, returns in New Super Mario Bros. U. Unlike the other inventories, however, this one is limited to ten items only. Players can add items into their inventory by playing red Toad House minigames, collecting items on the world map itself, or completing an Enemy Course.

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.

Trivia

 * 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., bearing a resemblance to Waluigi
 * When the player grabs a Baby Yoshi, an additional choir is added to the music. Additionally, the Baby Yoshi will mouth to the choir.
 * When the Mario Bros., Toads, or Miis are not moving, they stop and stare at the screen until the player starts moving them again.
