New スーパーマリオブラザーズ
"New Super Mario Bros. U", the Wii U follow-up to "New Super Mario Bros. Wii", was released in November 2012, in North America. It plays similarly to the previous "New Super Mario Bros." games, and introduces both a Flying Squirrel suit that lets the players glide through the air, and asymmetric gameplay that allows the player holding the GamePad to influence the environment. In June 2013, "New Super Luigi U" was released as a downloadable content (DLC) package for the game, featuring shorter, but more difficult levels, starring Luigi as the main protagonist instead of his brother. Subsequently, it was released as a standalone retail game on August 25 in North America. Unlike the downloadable content version, the standalone retail version of "New Super Luigi U" does not require having "New Super Mario Bros. U" to play it. The Nintendo Switch port "New Super Mario Bros. U Deluxe" includes both the main game and "New Super Luigi U", and new playable characters Nabbit and Toadette.
