Early this morning, Koei Tecmo released a video in Japanese revealing the impending existence of Hyrule Warriors for 3DS. Then, the video soon vanished. It looks like one of E3’s surprises was let out of the box by accident.
The original Hyrule Warriors was based on Dynasty Warriors, Koei’s long-running brawler where you have to beat ten zillion enemies at once in a massive gauntlet. Hyrule Warriors plays similarly, but with the addition of Zelda characters, locations and themes. From the looks of things, Hyrule Warriors for 3DS will be the same game only with some new characters, notably Tetra and the King of Hyrule, both from Legend of Zelda: Wind Waker. The end of the video also suggests you’ll be able to transfer Tetra and King to the Wii U version of the game.
Normally Nintendo is better than any other company at preventing leaks this large. Documents and photos squeak out every now and then, but an entire video seldom ever happens. Though this was probably more Koei’s fault than theirs.
Before the video vanished from YouTube, it was re-uploaded on Polygon’s server. You can see it here. In addition, a screenshot from the video, which is available below, indicates compatibility with the original Wii U version.
