This is unmissable going through the story.
*** Spoiler - click to reveal ***When you head to Psychotronics, you will get to a point where you can't go any further unless you have the Psychoscope and will have to enter into the clean room on the men's side. Inside you'll find a hole in the floor. Drop down to find the Psychoscope. After this, you'll need to scan a few mimics to unlock your first Typhon power, Mimic Matter I. Once unlocked, spend a neuromod on it to purchase it, which will unlock this trophy.
