Upon discovering a Pokemon, the game will switch to battle mode where players will be able to call up three Pokemon by scanning their Tretta, a square card-like device with Pokemon pictures on top of them. We guess to a certain extent these cards could be thought of as a pokeball. The method of catching a Pokemon appears to be the same as the console version where you throw a pokeball in order to capture it. Apparently when you successfully capture one, the machine will dispense you a new Tretta. The game is expected to come out in July, although no word if it will be made available in arcades outside of Japan.
