Psychoseismometer is one of the many collectibles in collectibles such as Emotional Baggage, Figments, Nuggets of Wisdom, and more. In order for players to unlock the mission to find Psychoseismometers, they will have to have fixed Hollis' mind at this point to send out the fragments of Ford Cruller. These are the third and fourth areas in the game and can be completed within the first few hours.

After Raz reunites with his family, players will be able to explore the Questionable Area and the Quarry. Head across the lake to find a giant tree, climb to the top to find a treehouse. Inside, players can speak with Gisu to begin their hunt for the Psychoeismometers.

Fortunately, all 3 of them are fairly close to one another. Although, it is important to mention that each Psychoseismometer comes along with a fight so players will want to prepare beforehand by purchasing healing items at Otto's. Here is where players can find them all.

  • Psychoseismometer #1: This one can be found at the Quarry in the location that leads to the cave to the Questionable Area. Players will grind across two rails located in front of the Psychoisolation building then use the trapeze to a ledge over the Quarry. There will be a sign to Blastcap Becky Cave with an entrance covered in cobwebs directly next to it. Use Pyrokinesis to get inside and make it to the end of this path to find the first Psychoseismometer.
  • Psychoseismometer #2: This one can be found at the Questionable Area. There will be a wooden sign that reads "Campfire?" and bushes to the left of the sign. Players can climb the pole in these pushes to reach a walkway in the trees. Follow the path and jump on the yellow mushrooms. There will be a gust of air for players to jump in and they can use their levitation powers to reach the walkway on the other tree. Players will then fight against a few enemies. Defeat them to grab the Psychoseismometer.
  • Psychoseismometer #3: Located through the entrance to the Questionable Area's main location, there will be a path on the left. Take it to find a broken bridge and then take another right to reach the Aquato Campground. From this entrance, head left to find 2 rocks that players can climb. There will be a cave blocked off by rocks so Raz can use his PSI Blast attack to get inside. Take on more enemies within the inside to grab the final Psychoseismometer.

Now, head back to Gisu to complete this quest. Raz will be rewarded with a handful of Psitanium. Players can now continue to explore the Quarry or return back into the main story.
