Ratchet & Clank: Going Mobile is an action platformer that was developed by Handheld Games and published by Sony Pictures Mobile, exclusively for mobile phones. It was released on November 11, 2005 in only North America. Because of the platform, it was the only 2D game released in the franchise.
Both Ratchet and Clank were sent to preview some new technology, until it was accidentally activated and transported them into a Vid-comic, which is housed by your actual phone. The game has a total of twelve levels, as well as seven weapons, but only four basic enemies and the final boss. There was a sequel in development, called Ratchet & Clank: Clone Home, but it was cancelled.
