One of the strongest aspects of the PS3 is the large amount of really good exclusive titles available for the platform and the Ratchet and Clank series has been a mainstay on Sony’s console since the PS2 days. So far Ratchet and Clank have seen two full releases and one PSN title on the PS3. On October 18th the platforming duo will get their third full release with Ratchet & Clank: All 4 One. This version will be the first game in the series to feature 4 player co-op, so it should definitely feel fresh. Check out the video below featuring Ratchet, Clank, Dr. Nefarious, and Captain Qwark fighting a giant boss.
