Ratchet and Clank: Up Your Arsenal Part 25: Plot Twist

So, after completing the Fourth Comic Book, Ratchet gets the idea that Dr Nefarious might attack Metropolis since he had once sworn revenge against that world. Based on that little bit of information from a comic book game, Ratchet and Clank head on out to the world where, surprisingly, they were correct. As it Turns out, Nefarious was planning on turning all the living things on Metropolis into Robots using his new machine and, on top of that, we (the players) get to see a little bit of a plot twist that Ratchet won't notice until next video. Although, that being said, the game has hinted the idea several times already so it's more like they are confirming it.
