Even Nintendo isn't safe from pre-order incentives.
Hyrule Warriors will have special costumes if you pre-order the game from select retailers.
At the end of tonight's Nintendo Direct for Hyrule Warriors, Nintendo revealed various costumes for Link and Zelda, only accessible through pre-ordering the game. The costumes are taken from various 3D Zelda titles, including Ocarina of Time, Twilight Princess, and Skyward Sword. Those who register the game on Club Nintendo will also be getting alternate costumes for Ganondorf, inspired by his outfits in Ocarina of Time and Twilight Princess.
It is unknown which retailers will be participating in the pre-order bonuses, nor if Nintendo will be selling these costumes seperately on the eShop, but we will keep you updated when we receive more information
