Ratchet & Clank: The Lost Frontier, better known as Ratchet & Clank: The Last Adventure in PAL Countries, is a game for the PlayStation 3. Developed by Insomniac Games, this will be the longest game in the series, especially because this is the last game in the series before they go on to work with the Clank & Klunk series. Also, this game serves as the epilogue of the Ratchet & Clank series. Since it is the last game in the series, it will also release for the PlayStation Store by September.
