The Legend of Zelda: Ocarina of Time Master Quest

The Legend of Zelda: Ocarina of Time Master Quest was originally an expansion to Ocarina of Time planned for Nintendo's ill-fated Nintendo 64DD addon. When the 64DD failed in Japan, Nintendo cancelled the release of Master Quest. As time went on the nearly complete game sat wasted and unplayed. Nintendo decided to change this when they announced that they were bringing Ocarina of Time to the GameCube along with the legendary Master Quest, and would be offering both as part of a special pre-order campaign for The Wind Waker.

In 2011, a port of Ocarina of Time was completed for the Nintendo 3DS titled The Legend of Zelda: Ocarina of Time 3D. This game includes a version of Master Quest, titled The Legend of Zelda: Ocarina of Time 3D Master Quest, that features mirrored maps. This means that in the original Master Quest if you were to turn left at a given spot, in 3D Master Quest you would turn right, and vice versa.

Master Quest remixes the original dungeons present in Ocarina of Time and makes them much more difficult to complete. However outside of the dungeons nothing has changed, and many of the secrets and collectibles are in the same places they were in Ocarina of Time. There are currently two ways to acquire this game. One is via the special pre-order disk for the Nintendo GameCube. Although the discs are clearly labeled as "not for resale" game retailers still regularly buy and sell used copies of the game. It is also available as an unlockable feature in Ocarina of Time 3D, where it can be unlocked upon completion of the original quest. In the 3DS version of Master Quest, the entire game world has been mirrored, and all enemies cause double damage to Link.
