How to crack the safe!

The first safe you'll encounter in the Call of Duty: Black Ops 6 campaign is during the main mission The Rook: Arrival, and you'll need to solve the safe code combination to open it. Scattered around the safehouse are a series of clues and puzzles that will eventually lead you to a radio recording, which reveals the combination. The safe is housed in a bedroom on the top level of the safe house.

The Basement Boiler Room Puzzle Guide

Just to the right of the main briefing room is a hallway with a door immediately to the right. Open that door and head downstairs to a room with a big table. Continue through that room, through the door on the right, to enter the boiler room.

On the table to the right of the boiler is a note that explains how to solve the boiler puzzle.

Press buttons in the following order:

Boiler x2 (to close it completely and stop the leak)
Fuel x1 (to halfway)
Pilot x1
Boiler x2(to full)

If done correctly, the pilot light will turn green.

The Piano Puzzle Guide

Enter the room to the left of the briefing room to spot a piano. On the table in front of the piano is a blacklight, pick it up as it is required for the rest of the puzzles. Five piano keys need to be pressed in a particular order. Using the blacklight, you'll see the order painted around the room, with arrows pointing you to the next key to press.

The scribbled instructions will be in the following order:

Mn
Pe
Cn
Ao
Pe

Interact with the piano. Using the blacklight above the keys, you'll see that each key has a corresponding set of two letters. The keys need to be pressed in the order they are written on the walls. Press the keys in the following order: 54234.

The Keypad Puzzle Guide

After solving the piano puzzle, a secret door to the right will open, leading down to a hidden basement. Go down the stairs and continue down the hallway. You'll soon reach a fork, with pathways in front of you and to the left. Look to the right to spot a door with a keypad.

Using the blacklight, you can see fingerprints, indicating what keys have been pressed. After entering a random set of numbers based on the fingerprints, the decryption log on the right will show which numbers are in the correct spot by lighting up green. If a number is highlighted in yellow, this means that the number appears in the puzzle, but is just in the wrong spot.

Just note that this is random, so your solution may be different. The instructions above apply to whatever your solution may be. Just think Wordle, with numbers!
Computer Hack Puzzle Guide

After solving the keypad, enter the room. In the back corner, there is a computer for you to hack. There will be three code words to solve, and you'll get the answers by punching in the letter that corresponds with the digits of the codeword.

The solutions is:

BUNKER
HOLDING
ROOM
OPEN

Lockpick Puzzle Guide

Exit the computer hack room and immediately turn right. At the end of the hall, there is a door to the left. Enter it, and continue straight to see another door with a lock that you can pick.

Move the lockpick slowly until it glows white. Once it glows white, hold it in place until it clicks. Do that two more times to unlock the door. Inside that room is a small table with a key on it. Grab it and then exit the room.

Radio Signal - The Rook Safe Code Combination

After exiting the lockpick rooms, head back down the hallway, and at the fork, make a right. Continue down the hall and use the key to open the door on the left.

Toward the back of the room on a bookshelf is a radio, indicated by the signal strength icon. Interact with it to turn the frequency. Twist the frequency and amplitude knobs until the wavelengths match.

Once they do, you'll hear one of several random recordings. If you shine your blacklight around the room, you'll see that numbers are painted on several items. Based on which recording you got, it could be one of several solutions.

Safe Location

With the code memorized, head back upstairs to the main Rook briefing room. To the right, past the basement hallway, is a set of stairs leading to the second floor of The Rook.

At the top of the stairs, do a quick 360 to run down the hall -- the railing will be to your right. At the end of the hall is a door to your right. Enter it, and then go through the next immediate door to the right.

In the back right of the room is a bed, with the safe to the left of it. Enter your combination to receive your prize!
