The Pokémon franchise has long been tied to Nintendo-branded consoles, but that's all about to change with Pokémon Go. The mobile game for iPhone and Android smartphones will bring the adventure to a mobile device near you. Judging by the trailer, Go could offer an augmented reality adventure, allowing users to trade and battle against friends. Prior to an official release, the game's developer Niantic have issued field test versions of the game to eager fans. We first saw Japanese players able to play the Pokémon Go early, now American players will get their turn later this month.
