New Super Mario Bros. Wii

New Super Mario Bros. Wii is a sidescrolling Mario game announced for the Wii, to be released Holiday 2009. It is considered to be a sequel to New Super Mario Bros., a 2006 game released for the Nintendo DS. It features a multiplayer mode up to four players. It will feature more items, more levels and more enemies than the DS version of the game.

Story
Nothing in particular has been revealed. Morton Koopa Jr. is seen in a screenshot of this game suggesting the other Koopalings are in this as well.

Gameplay Features
The regular mode of the game can be played in single-player or multiplayer cooperative mode. Players can be freely added and removed between levels. As in Super Smash Bros. games, the camera zooms out when players move farther away from the screen. However, there is a limit and players who are far behind can still be kicked out of the screen. When a player dies, he reappears in a bubble. Other players can burst that bubble to allow the reappearing player to continue playing, or they can wait to be able to collect more power-ups for themselves. ? Blocks usually create one item for each player - for example, a block produces four mushrooms when four players are playing. Players can cooperate by picking each other up. Also, Blue and Yellow Toads are playable in Multiplayer.

When one player grabs the flagpole at the end of the level, the other players have about three seconds to grab it as well if they want to score points with it. If they don't catch it in time, the level still ends. After that, players get a tally telling players how many coins they have collected and how many enemies they have stomped. The players are ranked according to those points.

The basic style of the game resembles New Super Mario Bros. on the Nintendo DS. Players can collect Star Coins and find secret pipes. Parts of the ground have been seen moving.

Players play the game holding the Wii Remote sideways. Shakes of the Wii Remote can active certain items, such as the Propeller Suit.

It's possible to ride on Yoshi as well.

Development
According to Nintendo, Shigeru Miyamoto has been struggling to add multiplayer in a Mario game for a long time. He further explained that Miyamoto tried to experiment with multiplayer aspects at the start of most of his Mario projects. But when this experiment failed, the developers and the players focused back to what they are used to, single-player. One of the reasons this was not achieved previous is due to technical limitations. With the Wii's hardware, it allowed him to make sure the game had all the items and enemies in the screen at once, and having the camera focusing on all the players at once.
