The Legend of Zelda: Twilight Princess HD is the Wii U remaster of Twilight Princess, the 2006 adventure for GameCube and Wii. Nintendo announced it in a Nintendo Direct in November 2015 and released it on March 4th, 2016, alone or in a bundle with the new Wolf Link amiibo. Tantalus Media handled the remaster while Nintendo's own team worked on Breath of the Wild.
The story is unchanged: Link, a ranch hand from Ordon Village, is dragged into the Twilight Realm, turns into a wolf and teams up with the mysterious Midna to save Hyrule. The HD version sharpens the graphics to 1080p and uses the GameCube layout with a left-handed Link. It also trims the Tears of Light hunt to 12 per province, makes every wallet bigger, adds the Poe-finding Ghost Lantern, offers a Hero Mode from the start, and adds a 40-floor amiibo dungeon, the Cave of Shadows. Our What's New page lists every change.
Our guides cover the HD version: a full walkthrough, the Cave of Shadows, all 45 Heart Pieces, 60 Poe Souls, 24 Golden Bugs, the seven Hidden Skills, the Cave of Ordeals, every boss and the items.
