Black Ops 6 Secure Code and Puzzle Solution

You can open the on upstairs in the hideout Black Ops 6 to get money and Case Crack melee plan.

THE security code in Black Ops 6 is slightly random, so you must first solve the other puzzles in the shelter if you want to unlock the “Puzzles, the Mason” achievement or trophy in addition to collecting your rewards.

If you’re not interested in accolades, we’ve listed all the possible awards. Black Ops 6 Security Codes below, but have also detailed the safe puzzle solution for those who want to display this trophy/achievement, or are just curious how this is resolved.

Black Ops 6 Security Code

Here are all the possibilities Black Ops 6 Security Codes that we have encountered so far:

• 1836
• 2087
• 3196
• 4037
• 5024
• 7409
• 8935

The code that works for you depends on the phrase you receive from the radio in the basement, after you have solved all the other puzzles in the shelter. Once the phrase starts repeating, you need to match its clues with the numbers printed all over the room where the radio is located.

To see the numbers you need to use the backlight located in the piano room on the ground floor.

For example, the sentence during our first game was:

He plopped down on the couch, his wife’s purse still missing. He noticed the calendar marked with his brother’s birthday, just under the commemorative flag.

So we looked at the items mentioned in this sentence with the backlight on to get the code 3196.

Once you have your code, go up the stairs that are in the downstairs lobby, then turn left and enter the bedroom to find a safe next to the bed at the end. After entering your correct code, you get $1,000, the Case Crack melee blueprint, and the “Puzzles, Mason” achievement/trophy will also appear if you have solved the other vault puzzles on your path to cracking this chest -strong.

Black Ops 6 Safe Code Puzzle Solution

Here are the step by step instructions on how to solve the secure code puzzle in Black Ops 6:

1. Go down to the boiler room.



2. Turn the boiler valve in the middle to zero, the fuel line on the left to 50, then press the “Pilot” button on the right.
3. Return to the boiler valve and turn it to 100.
4. Go to the ground floor and collect the backlight from the piano room.
5. Solve the piano puzzle to open the door to the basement, to the right of the piano.



6. Go down the hallway and turn right to find a keypad near a locked door.
7. Find the correct code, Wordle style, by entering digits with a fingerprint on them (this will reset and change the numbers after five attempts).



8. Enter the server room and solve the computer cipher by matching the numbers with the letters, as shown in the cipher at the bottom of the screen (the code will always be some variation of the words Holding, Room, Bunker, and Open).



9. Exit the server room and turn right to the end of the hallway, then go through the now unlocked door.
10. Pick the lock on the interior door, Skyrim style, by gently rotating the controller’s right stick or your mouse on the PC, then hold there for a few seconds when each spring begins to glow.
11. Collect the key in the room you picked the lock in, then go back down the hallway and turn right to enter the room near the “Weak Signal” pop-up message.
12. Change the frequency and amplitude on the radio until the waves match.
13. Listen to the phrase on the radio, turn on your backlight and look for the objects mentioned in the phrase inside this room.
14. Write down the numbers found on these items in the safe upstairs in the room.
