King Mickey and Yen Sid prepare for an impending threat by putting Sora and Riku through the Mark of Mastery exam. Sora and Riku are sent into the Sleeping Worlds, where they will face enemies and allies that have never been seen before. If they can successfully complete the task they are given, they will be deemed true Keyblade Masters. Creatures called Dream Eaters inhabit the Sleeping Worlds, and are split into two categories: Spirits and Nightmares. There are over 50 types of Spirits that can become allies and fight alongside Sora and Riku. With brand-new gameplay features, worlds and creatures, KINGDOM HEARTS 3D [Dream Drop Distance] continues the tradition of engaging entertainment.
