Ratchet & Clank: Part 11: A Pilot's Helmet in Gaspar
Gaspar feels like another detour planet but you still need to take this "detour" to find a gadget that you'll need later in this game. In this case, it's the Pilot's Helmet
----------
There is an elaborate Skill Point here called "Destroyed", where you go through an entire alternate route to blow up all of those huge ships called Blarg Destroyers. Specifically, you need to destroy the machines they're connected to, and the ship will soon go down with them. There should be a Gold Bolt at the end of this course.
Another Skill Point is called "Gunner". There are turrets on the main route of this planet that lets you destroy metal doors, but you can also use it to blow up the ships in the sky. Normally, you have to shoot down 5 ships to get this Skill Point, but I think since I loaded this game file up from one where I already did this, I only had to destroy one.
----------
The main route is mostly straightforward where you're just fighting through loads of enemies to reach the Pilot's Helmet, which lets you control certain ships. Ratchet & Clank don't get to talk to anyone on this planet.
There's a secret route past that helmet that you'll have to dive into and underground to reach. Survive this area to go through a different path back to your ship, and even pick up another Gold Bolt when you get close.
----------
One new weapon you can get from here is the Walloper. It packs... a walloper! Since it's just a big punch, it's one of the only weapons that doesn't need ammo.
