Wii U GamePad:

By using the Wii U GamePad, players can now easily manage their inventory, access the map and quickly transform into a wolf via the touch screen, all without pausing the game. Players will also be able to use the GamePad to access Miiverse and can even play the game off-TV. Miiverse posts can be decorated with dozens of new Twilight Princess-related Miiverse stamps, hidden away throughout Hyrule.

Ghost Lantern:

The addition of a new item, the Ghost Lantern, will aid Link in the Poe Soul retrieving quest. When Link holds the Ghost Lantern it will helpfully glow when it detects a Poe in the area. Similarly, the number of Tears of Light that need to be collected by Link at various points in his adventure has been reduced from 16 to 12, making these collection tasks easier. Furthermore, if Link finds Rupees in a treasure chest while his wallet is already full, Rupees will no longer be returned to that chest. Players are also less likely to reach the limit of their wallets, as these have been modified to hold more Rupees.

Hero Mode:

Zelda veterans or brave new players who desire an added challenge can opt to play in Hero Mode right from the start. A testing new way to play through the main adventure, in Hero Mode Link will take double the normal damage and there are no health-replenishing hearts to be found. In a final layer of challenge the game world is also mirrored, so dungeon layouts will be reversed. For those in search of the ultimate challenge, tapping the Ganondorf amiibo on the Wii U GamePad when in Hero Mode will cause Link to take a staggering four times the normal damage until the play session ends.
