After Nintendo teased a new New Super Mario Bros. game during their pre-E3 conference earlier this week, they announced New Super Mario Bros. U officially for the Wii U during their main E3 presser.
They showed off a ton of gameplay, showing some extremely good looking and typically wacky Mario gameplay, and it looked really, really good. The visuals are noteworthy indeed.
They did not give any release date.
The full gameplay demonstration is given above. Take a look, enjoy.
