The following video is the first of four in a Ratchet and Clank: All 4 One extravaganza! This video showcases some of the ridiculous weapons from the Ratchet and Clank universe. You'll see the Combuster, the Warmonger, and others. Each weapon appears to have some form of co-op functionality. The Darkstar Fission Tether looks promising. Remember, this is just a taste of the available arsenal.
Ratchet and Clank: All 4 One has that co-op-iest of co-op modes, simultaneous local and/or online play with up to four players. It will be release on October 18th on the PlayStation 3. We'll be sure to bring you the rest of the gameplay videos as they become available. That'll make the wait for October all the more bearable.
