GameSpot writes: "Ratchet and Clank: All 4 One was unveiled last night at Sony's GamesCom 2010 press conference. There are two big features that separate this Ratchet from previous games in the series. For one, it's the first title to come from Insomniac's offshoot North Carolina studio that the developer opened up in early 2009. But more importantly, All 4 One will give players the chance to play through a Ratchet with co-op supporting up to four players. We just had a look at this new spin on the series courtesy of Insomniac, giving us a chance to learn quite a bit more about it than what we gleaned from last night's press conference".
