With all 3 gears now collected, you will need to head over to the 5th floor, and look with your camera to this wall to go through it and get to the secret area.

When inside this area, you will notice a blue security mechanism that you need to insert the blue car inside and writhe the following code:

  • 64582

Enter the area and look through the camera at this specific wall. Looking through it will show you a shelf with all the books that you’ve previously collected, including The 3 Musketeers book. Place that book there and organize all books in a specific order.

The correct alignment for all the books starts from left to right:

  • 1 Flew Over the Cuckoo’s Nest
  • A Tale of 2 Cities
  • The Bermuda Triangle
  • The 3 Musketeers
  • Slaughterhouse 5
  • 6 Years
  • The 6 Deadly Sins

With that order made, a secret door will open up and reveal you a mechanism that you can write down letters.

You will write the letters later in that room, now just turn around and look at the image on the wall that you can remove and slap the gears there.

With all 3 gears attached to the wall, simply put down the 3 letters for each gear on the white arrow.

The correct letters are TFM.

The last step is to enter the room with the mechanism that reads F O B I A and interact with it. Simply write down YHUBT on the machine and you will get your trophy!
