Nintendo revealed the existence of two new The Legend of Zelda titles, both for Nintendo 3DS. The first game is The Legend of Zelda: Tri Force Heroes, a spiritual successor to The Legend of Zelda: Four Swords Adventures.
Tri Force Heroes features three Links working together to get through dungeons. The game features both local and online multiplayer, with each player controlling one Link. In single player, two of the Links are replaced by AI dolls, with the player able to switch the one they are controlling on the fly. The game also features a costume mechanic, with different costumes bestowing different abilities. The Legend of Zelda: Tri Force Heroes is set to be released in Q4 2015, with the announcement trailer and some media below.
The other game is Hyrule Warriors Legends, a 3DS version of Omega Force's Hyrule Warriors that was released on Wii U. The game is crossover between Legend of Zelda and Omega Force's Musou titles. The 3DS version includes all the DLC characters from the Wii U version, and also adds in characters and stages from The Legend of Zelda: Wind Waker. Hyrule Warriors Legends is due to be released in Q1 2016, with a video also viewable below.
