Other than the Master Quest, it looks as though the other extra content included with Ocarina of Time on 3DS has been revealed.
According to a report which first surfaced over on VideoGameZone before being picked up elsewhere, a mode called Boss Rush which is a bosses-only battle is included and will allow players to challenge a defeated boss once more – or face all of them one after the other in constant battle.
A sort of Super Guide will also be included, according to the report, which will come in the form of small in-game videos with hints on puzzles.
Nintendo has more information on this for you here.
Game’s out in Europe on June 17 and the US on June 19.
