The Legend of Zelda: Majora's Mask 3D is a port of the original N64 action adventure title first released in October 2000. Like Ocarina of Time, the 3DS remake features stereoscopic 3D graphics and touchscreen support for inventory and equipment management via the bottom screen.
Majora's Mask puts players in control of young Link following the events of The Ocarina of Time. Tricked into entering a parallel world called Termina, Link must contend with a doomsday crisis involving nothing less than the moon threatening to crash land onto the land itself and wiping out all life in the process. Players have three in-game days to unravel the mystery of Majora's Mask in order to stop the moon, but they can use the magic of the ocarina to manipulate and even alter the flow of time.
Management of tasks becomes important as players must plan how they wish to tackle the dungeons of Termina to free the Four Giants who can help halt the moon. In addition to Link's weapons and tools, players will earn masks which allow Link to transform into one of three forms with their own abilities necessary to overcome various challenges throughout the game.
The flow of time and the day-and-night cycle also has an effect on the schedules of all NPCs, and players can keep track of their daily routines using a special notebook earned early in the game. Completing their requests will often require players to plan their actions across the 72-hour in-game period accordingly.
This game is also known as Zelda no Densetsu: Majora no Kamen in Japan.
