Ratchet & Clank: Part 15: Masking Up for a Drink in Orxon
9Now that Ratchet finally has the O2 Mask, he can now properly explore the toxic Orxon, himself. The music will even be different compared to when you explored this place as Clank.
This difficulty ramps up in this level. There are some claw monsters that can take quite a beating before they're killed. A Blaster will kill them each with 10 shots, but this will ride up on you quite fast since there's a lot of them in the planet. There will also be some Blarg ships that can easily be taken down with 3 Devastator rockets.
At 4:40, if you use the Blaster to shoot a blue screamer through a long hole, you'll get the "Sniper" Skill Point.
At 11:32, you can also get a Skill Point called "Hey, Over Here!" if you use the Taunter to lure those claw creatures to hurt and kill themselves against the force field.

One of the routes will let into a room with fresh air that lets Ratchet reach a Nanotech Dispenser. If you have enough Bolts, you can give him a drink and permanently increase his maximum health. If you have even more Bolts, you can then raise it even higher.
The other route will have an Infobot for you to chase after. Some of this chasing will involve using the Magneboots to reach different islands and climb steep walls.
At the end, the Infobot finally shows its message: Drek has moved on to planet Hoven, and is about to eliminate a different planet that getting in the way of the orbit he was looking for.
Although Ratchet was still focused on hunting down Captain Qwark, he didn't mind stopping Drek if he was along the way towards Qwark. Clank saw this as Ratchet slowly starting to be the hero he wanted to see him as, but Ratchet's vengance for Qwark is still complicating those matters with the duo.

At 17:30, there's a secret route via a mutant cave I can unlock that will lead to a Gold Bolt, but to unlock this route, you need to use the Visibomb Gun to open up the way from the other side. I spent quite a bit of time and Bolts for Visibomb ammo to pull this off.
