Play the Qwark vid-comic Episode 3 is a mission in Up Your Arsenal, taking place in the Starship Phoenix. Ratchet and Clank won the third Qwark vid-comic episode, Shadow of the Robot, from the Annihilation Nation while meeting Courtney Gears. The prize was presented to them by Courtney Gears herself, after they beat Scorpio in the challenge "Meet Courtney - Arena".
Shadow of the Robot can be completed at any time once it is obtained, but is required to progress with the remaining vid-comics. Completing it immediately after obtaining it can provide a boost in bolts which is helpful right away.
As before, it is good to aim for the hidden health upgrade, as this is helpful when completing other vid-comics.
