Nintendo has announced New Super Mario Bros U, a flagship platformer that will show off the connectivity of its recently unveiled Miiverse system.
The game was previously demonstrated last year as New Super Mario Bros Mii.
NSMBU will be your typical 2D platforming fare supporting up to four players. As was revealed on Sunday, the map screen between levels will be populated by comments and tips from other Miis in the Miiverse - people that Wii U owners are friends with, have met online or other users of the console.
Reggie Fils-Aime said users will also be able to connect with other Wii U owners while they're playing the game.
New Super Mario Bros U will also have a Boost Mode, whereby four players control Mario, Luigi and Toads with Wii Remotes and a fifth player can create helpful blocks using the Wii U GamePad.
