Rendezvous with Qwark

Go to Zeldrin Starport and Rendezvous with Qwark are missions in Up Your Arsenal taking place in the Zeldrin Startport. After Ratchet beat Courtney Gears, Sasha Phyronix informed him that the Q-Force had located Dr. Nefarious' star cruiser, the Leviathan, refueling at the Zeldrin Starport. The two traveled there and met up with Captain Qwark to attack.

Walkthrough
The mission is completed simply by heading left after landing in the Zeldrin Starport. This will commence a cutscene with Qwark, and lead directly into the next mission, "Find Nefarious".

However, before doing so, completing a segment in the Zeldrin Starport allows you to obtain the Bolt Grabber V2, which can significantly help your ability to obtain bolts. Do this before meeting up with Qwark, as completing the next set of missions will immediately take you away from the Starport requiring you to return.
