New Super Mario Bros. Wii

New Super Mario Bros. Wii is a 2D side-scrolling platform video game developed by Nintendo for the Wii. A follow-up to the 2006 Nintendo DS game New Super Mario Bros., it was first released in Australia, North America, and Europe in November 2009, followed by Japan a month later. Like other side-scrolling Super Mario games, the player controls Mario as he travels eight worlds and fights Bowser's henchmen to rescue Princess Peach.
