Those who missed out on The Legend of Zelda: Ocarina of Time Master Quest on its previous release as a bonus disc included with The Legend of Zelda: The Wind Waker, may be happy to know Nintendo will apparently be releasing it again. This time, the company is including it in the Ocarina of Time remake on the 3DS, presumably with improved visuals and not just a port.
A Nintendo representative has claimed this, though it's not 100% confirmed true yet.
Master Quest included everything the original game offered, but dungeons and temples were made harder with changes made to them. More enemies were also placed around and were made tougher to beat.
