"Pokémon Mystery Dungeon: Gates to Infinity (Japanese: ポケモン不思議のダンジョン マグナゲートと∞迷宮 Hepburn: Pokémon Fushigi no Dungeon: Magnagate to Mugendai Meikyū) is a game for the Nintendo 3DS. The latest installment in the Pokémon Mystery Dungeon series, it was released in Japan on November 23, 2012, in North America on March 24, 2013, and in Europe and Australia in May 2013.
The game features Unova Pokémon heavily, with Pikachu, Oshawott, Tepig, Snivy and Axew being the starters of the game. The game has a 3D art style and makes use of the 3DS' capabilities. Instead of the usual 2D sprites, the game utilizes more complex 3D models, and also uses the 3DS' camera and sensors for the players to find round objects and turn them into portals. The portals, called Magnagates (hence the title of the game) need to be unlocked, and act as gateways to new dungeons. The game also features 'augmented reality options'; by scanning objects in the 'real world' additional dungeons may be unlocked. The game features both free and paid downloadable content, in the form of additional dungeons."
