Ratchet & Clank: All 4 One trailer shows how to play single-player

Ratchet & Clank: All 4 One is Insomniac’s next addition to the R&C series, but this time, the puzzle-platformer-shooter-action game is built with four-player co-op in mind from the ground up.  

Insomniac is taking the chance to show us that you can still play as either Ratchet, Clank, Qwark, Nefarious in single-player, and the game will pair you up with an AI controlled version of the aforementioned characters. 

Ratchet & Clank: All 4 One will be released exclusively on the PlayStation 3 on October 18.
