Three dimensions, three Links.

A new, top-down 3D Zelda game has been revealed for Nintendo 3DS.
Tri Force Heroes allows up to three players to work together in a classic Zelda title similar in design to the previous Four Swords titles. Key features in this title are wearable costumes that provide Link with different abilities, such as dodging enemy attacks, and the ability to lift other Links on your shoulders, allowing for a totem pole formation when all three Links are stacked up as one.
It is worthy to note that the developer team at Nintendo attempted a four-player configuration for this game, but found that three worked best.
We'll update with more information as it becomes apparent.
