"Ratchet & Clank: All 4 One is Insomniac’s second multi-player focused game in the series. Back in 2005 they had released Ratchet: Deadlocked, which was a cooperative arena focused game where Ratchet and Clank fought for their survival in an intergalactic tournament. All 4 One, however, takes the more traditional single player story driven route of the previous games; the four most prominent characters in the series, Ratchet, Clank, Dr. Nefarious and Qwark are set against an unknown foe that is threatening the universe. Sound familiar? It should; that is the basic plot for every single previous Ratchet & Clank game."
