It's called A Harsh Climb. As you explore the ship, you'll eventually arrive at an officer's mess hall where everyone has frozen to death. You need to check out a few clues if you want to open the metal door. The Captain's Code clueThe first clue comes from the Captain's Code document. It has the following letters written on it: J--G-M.There are also two more Code Table documents in this room, but we'll discuss these in a while. Code CipherIf you check the room, you'll see several Code Tables--i.e. disks with letters--on the counter and on the floor. Pick these up and place them in the cipher in the correct order:First slot: The disk with the letter "J"Second slot: The disk with the letter "" (umlaut)Third slot: The disk with the letter "G"Fourth slot: The disk with the letter "M" Code Table and Captain's Code solutionOnce all disks are inside the cipher, dial in the letters until "J--G-M" are selected. Curiously enough, nothing happens. However, if you look at the letters below the "solution," you'll see that they spell out "B-L-U-T."Read the Code Table document again. You'll notice "B-L-U-T" has a corresponding numerical sequence: 3666. Interact with the panel on the door and input 3-6-6-6. This is the passcode for "B-L-U-T" and it will cause the door to get unlocked.That does it for our guide on how to complete the Code Table and Captain's Code puzzle in Indiana Jones and the Great Circle.
