New Super Mario Bros. Wii

New Super Mario Bros. Wii is a side-scrolling platform video game published and developed by Nintendo for the Wii video game console and is the sequel to New Super Mario Bros. for the Nintendo DS. The game was released on November 12, 2009 in Australia, November 15, 2009 in North America, November 20, 2009 in Europe, and December 3, 2009 in Japan. It is the first game in the main series since Mario Bros. to feature simultaneous multiplayer gameplay, as well as being the first side-scrolling console platformer starring Mario since Super Mario World on the SNES, and the first title to feature Nintendo's new 'Super Guide' feature.

The game follows the traditional storyline of Princess Peach getting kidnapped by Bowser. When Mario, Luigi, Blue Toad, and Yellow Toad are celebrating Princess Peach's birthday in her castle, a large cake rolls in. Immediately Bowser Jr. and the Koopalings pop out and throw the cake on top of Peach, trapping her. The cake is loaded onto Bowser's airship and takes off, with the Mario brothers and the Toads giving chase. The Toads in the castle then grant them access to the Propeller and Penguin Suits via a cannon. The player then goes through the different levels and worlds, facing the Koopalings, Bowser Jr., Kamek and finally, Bowser himself, in order to save Peach.
