European and North American release dates for New Super Mario Bros. Wii right inside!

Dubbed by Nintendo as the world's "first truly multi-player Mario game" New Super Mario Bros. Wii will launch in Europe on November 20th, and the U.S. from November 14th, 2009.

Players can co-operate or compete against one another in this new title, made in the same format as the classic side-scrolling Mario 2D adventures. Mario, Luigi and a pair of Toads are playable as you once again rescue Princess Peach from the clutches of Bowser.

Co-operate by saving your friends from danger - or get rid of the competition by tossing them straight into it. The game follows the style of New Super Mario Bros. for Nintendo DS with new twists utilising the unique features of Wii. The motion control capabilities of Wii have been cleverly implemented to enhance the gameplay at certain stages. For example, the player can angle a see-saw like platform by tilting the Wii Remote, to reach secret areas or angle the beam of a lamp to see the way in the dark.

New features in the game include the new propeller suit, which, by shaking the Wii Remote, allows your character to fly and hover - great for reaching secret areas. You can also use your suit to help your fellow players, for instance if another player picks you up, you can both fly together! There is a new penguin suit too which enables you to throw ice balls at your enemy, jump onto your stomach and slide with incredible speed across icy sections of a stage.

Players can even ride different Yoshis through the crazy and imaginative levels, using their tongues to swallow enemies - or their fellow players. New Super Mario Bros. Wii is also the first Nintendo game to feature a dynamic help system, which allows you to access a mode which allows you to watch how a level can be completed if you are stuck and jump into the action you're watching on screen at any time.
