Psychonauts 2 Questionable Area Supply Chest Keys just like those from the Quarry are needed not only to open the chests you find in the third area of the game, but all Supply Chests that have been hidden by the Double Fine Productions devs.
On top of this, they are required to get 100% completion in the Questionable Area, which makes them quite important.
Since the Psychonauts 2 Questionable Area Chest Keys are pretty hard to find; throughout the guide below we’ll discuss their locations, and how to get all 4 of them.
All Questionable Area Supply Chest Keys Locations
Before we move to the actual locations of these keys; it’s worth remembering that these items can be acquired in any order you want; but to save you some time, the locations guide below, takes you from the first area to the last one.
Furthermore, it’s also good to know that they do not require any special abilities, badges, or upgrades, so you’ll be able to get all of them the moment you enter the Questionable Area where Raz is looking for his family.
Questionable Area Supply Chest Key 1
Map Location: Entrance Cave
How To Get: When you enter the cave connecting the Motherlobe Quarry and Questionable Area, on the left side you’ll see some vines.
Use them to climb the cave’s wall and jump on the icicles to get the first Questionable Area Supply Chest Key standing on a stone platform.
Questionable Area Supply Chest Key 2
Map Location: B (Fierro’s Funicular)
How To Get: For the next Supply Chest Key you have to repair Fierro’s Funicular.
As such, you’ll need three cogs. Here is where to find them:
- The first one is in front of the Funicular
- The second one is by a large rock and a bench also in front of the Funicular
- The last one sits by the ramp leading up the mountain (left side while facing the ramp)
Use Raz’s Telekinesis to get the cogs and place them on the Funicular’s pins to get the train moving up the mountain.
The moment you reach the top, look behind the Questionable Gifts Shop (or what’s left of it) to get the key pictured below.
Questionable Area Supply Chest Key 3
Map Location: F (Forgetful Forest)
How To Get: On your way back from the Funicular stop by the campfire and find the blue toilets.
Reach the roof using the flagpole on the ground then hop on the ladder suspended by the wooden platform. Use the Levitation Ball if you can’t reach it.
Now, use the rope to get to the next platform, then go around it to find a flagpole.
Climb it and go around the tree to find one of the Psychonauts 2 Questionable Area Supply Chest Keys.
Questionable Area Supply Chest Key 4
Map Location: D (Campgrounds)
How To Get: The last Psychonauts 2 Questionable Area Chest Key is found on a platform above the area where Raz meets his parents.
This is quite easy to get as long as you know that you can use the campfire to create hot air.
As such, use Raz’s Pyrokinesis on the fire in the middle of the camp, then levitate and land on the platform where the Chest Key is waiting.
