Being an HD remake of a Legend of Zelda game should suffice for Nintendo loyalists. However, Nintendo's not content with making Wind Waker HD merely an old game with better graphics. No, they're tweaking a few things, adding a new features. For example, the Triforce fetch quest in the latter half of the game has been "greatly simplified."
Other new features for the Wii U version include being able to use the GamePad to take photos, write messages, and use Miiverse to help other players. But perhaps the most significant addition is a new difficulty mode, for those that want more of a challenge out of Toon Link's adventure.
Polygon discovered "Hero Mode" during their recent hands-on with the game. In Hero Mode, enemies deal double damage and players won't be able to find hearts in the environment. In fact, the only way Link will be able to recover health is through the use of potions or fairies. That's pretty hardcore.
The Legend of Zelda: Wind Waker HD will be out later this year.
