Insomniac has announced a new Ratchet & Clank game for the PlayStation 3. Yeah, we know you've heard that one before, but this time it's a four-player, online co-op platformer. Ratchet & Clank: All 4 One features drop-in / drop-out play between four characters, namely Ratchet, Clank, Quark and Dr. Nefarious. It's due in Fall 2011.

Dibs on Quark!
