New Super Luigi U

New Super Luigi U (styled as New Super Luigi Bros. U) is an upcoming expansion pack to the Wii U title New Super Mario Bros. U, celebrating The Year of Luigi. The title was announced during the Feburary 14, 2013, Nintendo Direct by Satoru Iwata. It features Luigi as player one, with Yellow Toad, Blue Toad and notably, Nabbit (who replaces Mario from the original game) as playable in multiplayer mode. Features like Challenge Mode and Boost Rush are not available.

The title will be released for the Wii U eShop, and can be purchased by accessing it via an Internet connection, and having a copy of New Super Mario Bros. U. Once downloaded, the player must press a certain button on the file select screen to play. It will also be available for purchase at retail. This version will not require New Super Mario Bros. U in order to be playable. Wii U Pro Controller support will also be included.

Gameplay
The gameplay is largely similar to its base game, except that Luigi retains his higher jump and lower traction from Super Mario Bros.: The Lost Levels. The game itself is also made harder, and every course starts at one-hundred seconds. Elements like Star Coins, Enemy Courses, and bosses are retained.
