The Legend of Zelda: Tri Force Heroes is the latest Zelda game to come to the 3DS. The game is focused on co-op and multiplayer. Up to three players can play, each taking the role of an individual Link character.
The 3D feature from A Link Between Worlds returns with a multiplayer twist in the form of the Totem Mechanic, which lets players stack on top of one another to reach new locations, solve puzzles, or fight enemies.
There will also be a single-player mode. The game is due fall 2015. The reveal trailer demonstrates the new features pretty well, so be sure to give it a watch.
