The Motherlobe is the first open-world hub you’ll visit in Psychonauts 2, and like the rest, you can only really clear it out of collectibles after you’ve finished the game. The collectibles in the real world are also very different from the ones in your mind — mostly, you’ll be hunting for PSI Cards, which can be used to give you a rank up. Very handy in the early game when you’re gaining lots of powers but want to make them even better.
To rank up with PSI Cards, you need to gain 9, then trade them in with a PSI Core. PSI Cores have to be purchased from Otto’s Shop for 25 psitanium, and there’s no other way to get them. You can also find rare rewards like PSI Markers, which give you an instant rank-up. The other collectibles are Supply Chests, which give you a huge infusion of Psitanium currency, but you’ll have to locate the hidden keys first. They’re all worth tracking down, and here’s where to get them all.
