Just what online features will Super Smash Bros. for Wii U have? Nintendo have outlined some of the game's functionality.
First up, the Wii U edition of the game will contain similar online features to the 3DS outing - public, friend matches, and also allow for two players to team up and take on the world together. There'll also be the inclusion of voice chat (via the GamePad) before and after battles; but unavailable during a fight for network reasons. Nintendo are also planning tournaments - both fan and official - in a future update.
As for content sharing, Nintendo will allow players to share their stage creations post-release, via an upcoming game update.
