Nintendo has announced Super Mario 3D World for Wii U, a game that takes elements from Super Mario 3D World on 3DS and New Super Mario Bros and introduces... Cat Mario.
It offers four-player co-op platforming action, with other players assuming the role of Luigi, Toad and Princess Peach. Team activities are included in the game, such as water rafting. A new power up allows characters to dress up like a cat and run up walls and scratch enemies.
The game is set to launch in December 2013. It'll also be available in Nintendo eShop.
