New Super Mario Bros. Wii
2009 side-scrolling multiplayer platform video game

New Super Mario Bros. Wii is a 2009 platform game developed and published by Nintendo for the Wii. A follow-up to New Super Mario Bros., it was first released in Australia, North America, and Europe in November 2009, followed by Japan a month later. It was released on the Wii U's Virtual Console in 2016, though only in Europe, Australia and Japan. A port in high definition resolution for the Nvidia Shield TV was released only in China in December 2017. Like other side-scrolling Super Mario games, the player controls Mario as he travels eight worlds and fights Bowser's army to save Princess Peach. New Super Mario Bros. Wii was the first Super Mario game to feature simultaneous cooperative multiplayer gameplay; up to four people can play in cooperative and competitive multiplayer modes, taking control of Mario as well as Luigi and two Toads, Yellow Toad and Blue Toad. The game also introduced "Super Guide", which allows the player to watch a computer-controlled character complete a level.
Shigeru Miyamoto had desired to create a Super Mario game with cooperative multiplayer since the series' conception.
