“Hyrule Warriors” for 3DS Leaked
More Pre-E3 Leak Shenanigans
Koei Tecmo accidentally revealed a video for "Hyrule Warriors for 3DS (please note that the video has been set to private for now.).
In addition to porting "Hyrule Warriors" to the 3DS, the game will be getting new characters Tetra and Daphnes Nohansen Hyrule, king of Hyrule and controller of King of Red Lions (both appear in "The Legend of Zelda: Wind Waker), along with new weapons.
There will be some connectivity between the 3DS version and the Wii U- most likely to get Tetra and Daphnes. Whether or not you need to buy the 3DS version to unlock the characters isn't known yet, but it most likely will be a similar case like Mewtwo for "Super Smash Bros." for Wii U/3DS where you can buy the DLC separately. We will update when Nintendo officially makes an announcement proper.
