On this page of our guide to Layers of Fear 2 we have prepared a detailed description of the safe riddle, which has to be solved during the first act of the game. You will learn where to find the combination of the safe and how to enter it properly to open the safe.
Puzzle with the safe occurs shortly after you have to squeeze through the tunnel.
After exiting the tunnel, start going to the right. In the place with image you will find a note with the combination to the safe.
Go back to the exit of the tunnel. Use the first rotary mechanism to open the huge door of the safe.
Only when you enter the vault can you interact with the safe.
The code to the safe is:
10 to the right (stop the rotating mechanism on the value of 10)
80 to the left (stop the rotating mechanism on the value of 80)
40 to the right (stop the rotating mechanism on the value of 40)
It is very important to keep the mechanism on each of these values and let it go for a while. You should hear a "click" confirming that a particular part of the combination has been entered correctly.
Pull the lever and pick up a shell from the safe.
