Ratchet and Clank 3 Up Your Arsenal Walkthrough
Zeldrin
This is a rough and rocky purple-themed world with dark clouds above. Shoot 3 birds at the starting area, and go down the magnetic path to the side for a titanium bolt.
Run and jump forward, and blast away at the enemies. You really want to be pretty high powered at this point with the best weapons and armor.
Dr. Nefarious trophy - in top right corner - up on a pillar.
Keep going forward, up the ramp. Soon you get to a hook-shot area. When you get down, you see an escape pod. Footprints! There's a recording, too. It's Quark in girly disguise calling for a taxi. You find a new data disk, too. It's the "Master Plan".
Go forward across the platforms and face the big robot. Go up the side of the building with your metallic boots and hop the lighting to the right. When you get to the very top you find a zip line. Take it down a long ride to your ship. You get a message from the robots - they need help. They're on Aridia.
You get back to the Phoenix and see that Skip is a robot - Al is trying to fix him. You get Episode 5 of the vid comic. "But only 4 issues were ever published!"
There's a nanopack on this map! At the point where the path bends sount, there's a dinosaur rib cage like structure before the elevator. Go through the tube and look up - there's a hookshot up there to get to. The nanopack stores extra health for you.
