Reaching the officer lounge

1. Officer lounge is one of the unique cabins on board the wreck of the Kummetz warship, which the heroes will explore during A Harsh Climb main quest in the Himalayas.
2. Upon reaching the officer lounge, you will find that the door to the next cabin is locked. You need a 4-digit combination - obtainable by using the cipher machine located here.

Cipher Machine puzzle, how to read the code?

1. Start by examining the center table with the frozen officers. The most important find is the captain's code. You will determine that the current code is JOGM.
2. Optionally, you can also find the first journal page - reading it will not help you solve the puzzle.

1. The key object to solving the puzzle is the cipher machine - it is shown in the attached image and you can take a photo of it before starting to solve the puzzle.

1. There are 4 code wheels in the area - 2 are lying next to the cipher machine and 2 are on the ground.
2. Pick up the wheels and zoom in to read the letters on them. Look for the letters J, O, G and M.
3. You must place the code wheels in the cipher machine - it has 4 slots and you must select the correct disks. Place the wheel with the letter J in the first slot, the wheel with the letter O in the second, the wheel with the letter G in the third, and the wheel with the letter M in the fourth. If you put the code wheel in the wrong place, you can remove it and select another slot.

1. Once the 4 wheel are in place, grab the top handle of the cipher machine to close it.

1. You can now rotate the placed code wheels to form the password JOGM. The code will appear in the lower windows - it is BLUT.

1. Return to the main table with the dead officers. One of the code tables is lying there.
2. Find the BLUT code in the list - we marked it in the image. You will determine that the combination of numbers associated with this code is 3666.

Entering the combination

1. Go back to the locked door and interact with the lock. Enter 3666 to unlock the passage and resume exploration of the shipwreck.
