Multiplayer dungeon-clearing adventures will return in The Legend of Zelda: Triforce Heroes, but with a bit more of a collaborative emphasis than in Four Swords. Nintendo announced the new 3DS title as part of its E3 2015 Digital Event.
Players work together to solve puzzles and take down bosses, even standing on each other's shoulders to form a three-player "totem" that can reach higher places. Apparently Nintendo decided a four-player totem would be a bit too tall, so Triforce Heroes will only allow for up to three Links to adventure together, unlike Four Swords.
You'll be able to play in local mutliplayer or in online, or take control of two other "doll-like" characters if you prefer to clear dungeons solo. Either way you'll find items which can be used to craft new outfits giving you special abilities, including samurai armor for an improved spin attack, lucky loungewear for a chance to avoid damage, and Zelda's royal regalia to make you feel like the princess you are (it probably has another power too).
The Legend of Zelda: Triforce Heroes will release in fall 2015.
