Trade brains for bolts

"A scientist can never have enough brains! He'll pay you for any brains you collect."

- Mission description

Trade brains for bolts is an optional mission in Ratchet & Clank (2016 game) taking place in the Blarg Research Outpost on planet Gaspar. After Ratchet and Clank gave the Brain Scientist 30 telepathopus brains in exchange for an XK-81 Jetpack and an infobot to Batalia, he offered them bolts in exchange for any more brains they brought him. Once they gave him all 60, he gave them a Box Breaker.

Walkthrough
There are 60 remaining brains on the planet. You can collect brains at any time throughout the story, such as when saving for powerful weapons like the Warmonger or Glove of Doom. However, it is ultimately best to return and complete the planet after acquiring the Map-o-Matic from Kalebo III. By this point, you should have bought more powerful weapons, and your weapons should be upgraded with Raritanium to make them more deadly against the enemies here, allowing you to survive longer.

As before, brains are found in egg sacks scattered throughout islands, or in live telepathopuses found near islands or caught in traps. A large group of brains are locked away in underground caves, accessible only by reaching a platform with blarg troopers on the far north of the map with a bolt crank, defeating the troopers and those operating the turrets, then turning the bolt crank to descend below to the cave. While you are here, there are also four gold bolts and one RYNO holocard located here.

When all brains are collected, the Brain Scientist will give you a Box Breaker, an optional item that breaks all nearby crates when you perform a hyper-strike.
