The Nintendo 3DS is getting its second Pokémon spin-off game before the end of the year. A CoroCoro magazine leak in Japan (via Serebii.net) reveals that Pokémon Mystery Dungeon: Magnagate and the Infinite Labyrinth is due out this winter.
CoroCoro’s article on the game says that you start out as a character that has turned into a Pokémon, having fallen into a dream. The game is in full 3D, and CoroCoro shows Pokémon from the Unova region. An augmented reality feature allows you to unlock dungeons by scanning objects in the real world.
More details can be found at the Serebii.net link above.
