Ideally, you'll play next month's PlayStation 3 exclusive Ratchet & Clank: All 4 One with three other people, online or offline. That's what it was made for. But in case you can't—in case you refuse—you can solo it. This new trailer shows what that looks like.
As you play solo, controlling Ratchet, Clank, Dr. Nefarious or Qwark, you get a computer-controlled buddy to simulate the co-op experience. Faithful Kotaku readers knew that already. We knew Clank would be that buddy for three of these heroes. We just didn't know who Clank's assistant would be. Thanks to this trailer, now we do.
