PSI King’s Sensorium is the Brain area that becomes available after Compton’s Cookoff, and as you’ll notice it is the largest in the game.
Inside, there are 4 Psychonauts 2 PSI King’s Sensorium Half-A-Minds collectibles you’ll have to find if you aim for 100% completion at the end of the game developed by Double Fine Productions.
And obviously to increase Raz’s health.
Throughout the guide below I’ll tell you where to find and how to get all 4 of them.
All PSI King's Sensorium Half-A-Minds Locations
Since this Brain is quite large and because of the powerful colors, you’ll most likely miss some collectibles.
Because of this, you should consider replaying each section of this brain after you beat the story, and get everything that you missed in the first playthrough, especially because both Memory Vaults require the Projection Badge.
The Half-A-Minds on the other hand can be collected in the first playthrough.
If needed, you should also consider using the following guides:
PSI King's Sensorium Half-A-Mind 1
Brain Location: Backstage
How To Get: The first Psychonauts 2 PSI King’s Sensorium Half-A-Mind is located in the Backstage area.
Specifically under the stage.
The moment you enter the level, head to the backstage area and look for an entrance under the ramp on the right side.
You’ll also find an Emotional Bag here. What you need to do to get the Half-A-Mind is to burn the poster in front of the bag, then hop through the hole.
Keep following the passage under the stage and you’ll find the collectible.
PSI King's Sensorium Half-A-Mind 2
Brain Location: Eye Shrine
How To Get: The location of the second Psychonauts 2 PSI King’s Sensorium Half-A-Mind also requires a keen eye.
This one is located in the second area you’ll get to visit while looking for the violin.
Once you unlock the Time Bubble Badge, you’ll reach two fans that must be stopped.
They are on some elevated wooden platforms, but the collectible is under them. Slow down the fans, grab the collectible then head up and slow them down again to cross.
PSI King's Sensorium Half-A-Mind 3
Brain Location: Woods
How To Get: The third Half-A-Mind is found in the Woods.
When you explore the waterfall area, you’ll eventually reach an upper section where you’ll be quite close to the water.
Here you’ll see the collectible on the other side (left) while you are on the right side. It is basically on top of the waterfall.
To get it you need jump and glide.
PSI King's Sensorium Half-A-Mind 4
Brain Location: Nose Mouth Shrine
How To Get: The fourth and final Half-A-Mind in PSI King’s Brain is found in the Nose Mouth Shrine.
It is fairly easy to find since it’s sitting on top of a tower immediately after the first 2 large moving tongues.
You can get there by activating the rainbow, or by sliding down a pipe from the top of the mountain.
That’s everything you need to know about the four Nuggets of Wisdom locations in PSi King’s Sensorium level of Psychonauts 2.
