The first image sof CoroCoro has been revealed, showing a new game for the 3DS coming this winter called Pokemon: Mysterious Dungeon: Magnagate and the Infinite Labrynth. It's coming to Japan this year. In this game, you start off as a character who turns into Pikachu as you fall into a dream. Partner Pokémon are Oshawott, Axew, Snivy & Tepig. This game is in full 3D. Unlike past games, this game appears to be standalone, rather than having two versions
It features a variety of Pokémon including Pokémon from Unova such as Gurdurr, Hydreigon and Virizion. You receive Quest Requests from Dunsparce, Cofagrigus runs a store, to which we don't know the details. Rampardos runs the Treasure Store. Kecleon returns, having the usual Goods store, with many items around it.
