Hey!

There are 5 achievements. You can't really miss any of them, so you will unlock them by finishing the game (please check the timestamps bellow).

0:00 = Power Restored (Bring the submarine’s lights back online) - you have to turn on some of the light switches to move the gauge needle into the green. The switches are random, so it will be different in your game.

0:36 = Under Pressure (Stabilize the submarine’s pressure system) - solve the valve puzzle. I turned all the valves fully to the left, then moved each one 1,5 spokes to the right.

2:05 = Shattered Mind (Reach zero sanity for the first time) - this should unlock automatically while doing the valve puzzle.

2:31 = False Death (Killed in the dark, yet the story goes on) - after the monster breaks a submarine’s window, you will wake up alive.

3:47 = Embrace the Light (Step beyond the hallucination and face the truth) - finish the game.

If you have any questions, suggestions, criticisms, found any mistakes and so on, please let me know!

Thanks to the developers for making a good game and thank you for checking out my guide!
