Nintendo announced during their Nintendo Direct that Super Mario 3D World will be released this December for the Wii U. The game will be avaiable in retail as well as on Nintendo eShop.
Super Mario 3D World will take a step forward in a different direction, to bring some inovation to the series, by adding a multiplayer mode for up to 4 players. The characters avaiable are the same ones that we could choose in Super Mario Bros. 2: Mario, Luigi, Peach and Toad.
Another innovation is a new ability that was introduced: a power that allows different characters to transform into cats. This power-up will allow players to scratch enemies and climb walls. Adding to this, players will be able to use the touch screen on the Wii U to find hidden hidden objects.
