New Super Luigi U

New Super Luigi U (stylized as New Super Luigi Bros. U) is a 2013 platform game developed by Nintendo for the Wii U. It is an expansion pack for New Super Mario Bros. U (2012), part of the Super Mario series. The plot and game mechanics remain identical to New Super Mario Bros. U, but Luigi replaces Mario as the protagonist. Luigi jumps higher and has less ground friction than Mario, and every level is redesigned to increase the difficulty level. The expansion adds Nabbit, a non-player character from New Super Mario Bros. U, as an invincible playable character.
