The Psychonauts 2 Motherlobe Challenge Markers are harder to find compared to the Challenge Cards in this area; but as you’ll find out, for each Challenge Marker you collect, Raz gains one rank.
Since there are 8 PSI Challenge Markers in the Motherlobe area, it means that you’ll level up Raz eight times simply by finding these collectibles. So below I’ll tell you where to look for them.
All Motherlobe PSI Challenge Markers Locations
Before moving on with the actual locations, you should be aware that not all collectibles listed below can be collected the first time you get to the Motherlobe.
In fact, only the first 4 in this guide are available early in the game, the rest of them requiring specific badges, gadgets, and upgrades, as explained.
Motherlobe PSI Challenge Marker 1
Map Location: 4 (Sasha’s Lab)
How To Get: Once you manage to escape the Storage Room, you’ll find yourself in Sasha’s Lab.
The moment you enter this area, look around and you’ll spot the first Psychonauts 2 Motherlobe PSI Challenge Marker in Sasha’s Office on top of a cabinet.
Obviously, you can return here later if you miss it.
Motherlobe PSI Challenge Marker 2
Map Location: M (Classroom)
How To Get: One tricky marker is found in the Classroom.
During your first visit here (or later) make sure you check the area under the stairs.
This is one of the Psychonauts 2 Motherlobe Challenge Markers that can be easily missed.
Motherlobe PSI Challenge Marker 3
Map Location: F (Mailroom)
How To Get: For the next Challenge Marker in Motherlobe, head to the Mailroom.
You’ll find it in the room where you need to sort the mail, but on a ramp, close to the ceiling.
To get there, jump on the boxes on the left side while facing the sorting station, then keep jumping on the conveyor belts.
Motherlobe PSI Challenge Marker 4
Map Location: J (Noodle Bowl)
How To Get: After you pick the previous marker, walk to the Noodle Bowl cafeteria.
On the right side, as you enter, you’ll see some ivy on the wall.
Jump on it, collect the Challenge Card, then keep moving up to spot the fourth Psychonauts 2 Motherlobe PSI Marker. Jump on the appliances to reach it.
Motherlobe PSI Challenge Marker 5
Map Location: A (Lobby)
How To Get: The next Challenge Marker in Motherlobe is the one in the Lobby.
This one is a bit trickier to get as it is on a suspended platform between the entrances to the Agents Area and the Mailroom.
Although you can reach this platform early in the game by jumping on the yellow monitors under the platform, and then gliding, this collectible is best approached after you get the Thought Scanner from Otto in the Quarry.
With this gadget, scan the area near the Classroom ramp (left side while facing the entrance), to reveal some nodes. Use the Mental Connection to get to the platform.
Motherlobe PSI Challenge Marker 6
Map Location: C (Office Of The Grand Head)
How To Get: For the Office Of The Grand Head PSI Challenge Marker you’ll need to progress through the story and eventually you’ll be asked to talk to Truman.
He’ll give you his access card which allows you to unlock the door to his office.
Inside you’ll find the sixth Motherlobe Marker, pictured below.
Motherlobe PSI Challenge Marker 7
Map Location: F (Mailroom)
How To Get: The next PSI Challenge Marker is in the Mailroom, but it requires the Projection Badge.
You’ll see it behind a locked door but you won’t be able to unlock it without the said Badge which is unlocked while playing Cassie’s Collection level. This is close to the end of the game.
Once you get the badge you will be able to open this door.
Motherlobe PSI Challenge Marker 8
Map Location: G (Astral Lanes Bowling Alley)
How To Get: The last Psychonauts 2 Motherlobe PSI Challenge Marker collectible is found in the Astral Lanes Bowling Alley.
Keep in mind that this area won’t be available at first, but you’ll unlock it once Raz fixes Ford’s Brain. Or what’s left of it.
The collectible is found on top of the large bowling pin at the entrance. While standing on the counter, just jump to get it.
