Hyrule Warriors will have “Premium Box” and “Treasure Box” editions in Japan, which will come with a few bonus items aside from the game. The main attraction in both boxes is a clock shaped like the Triforce, and Tecmo Koei recently revealed (thanks, Zelda Informer) what it looks like:
Aside from the clock, the Premium box will contain the game, an official booklet and six character costumes. Meanwhile, the Treasure box will contain the game, an official booklet, the clock, eight character costumes, a treasure box with sound, and the scarf that Link wears in the game.
The Premium Box can actually be ordered via Play-Asia if you care to import it. Meanwhile, the Treasure Box is exclusive to Amazon.jp and Game City.
Hyrule Warriors will be released in Japan this August. A western release will follow in September, although Nintendo have not announced any special packages or bundles for the game in the West yet.
