Safehouse in Call of Duty Black Ops 6 features various puzzles and secret locations hidden throughout the manor. Some are tricky to solve, but once you’ve played the correct melody on the piano and activated the boiler, you're nearly there. The last step is to obtain the safe code. Since passwords are randomized, you can’t rely on codes from other players, but with our step-by-step guide, you’ll complete this challenge in no time.

Black Ops 6 – How to Solve all Basement Puzzles

After you open the secret door near the piano in the Safehouse and solve the boiler puzzle, you’ll gain access to the basement/KGB bunker. To open the door with the keypad, you’ll need to enter the correct 5-digit decryption code. This code is random, so you’ll have to figure it out yourself. But don’t worry, it’s not as hard as it sounds.

You’ll need to try different combinations, but there are clues to guide you. If a digit isn’t part of the code, it will show up red. A digit in the wrong position will appear yellow, and the correct digit in the right place will be marked in green.

Once you get inside, you'll enter a computer room in the bunker. Your task here is to hack the PC, which is fairly straightforward. You’ll need to type four words that match the code displayed at the top of the screen. Each number corresponds to a different letter, as shown at the bottom of the screen.

Next, you’ll need to find the key to the room with the radio. Exit the computer area, turn right, and enter the leftmost door at the end of the corridor. Pick the lock on the door to the next room by rotating the lockpick, then grab the key from the small table beside the chair.

Finally, open the door to the last room in the bunker and turn on the radio. Adjust the Amplitude and Frequency dials until the wave colors turn green to get the code to the safe on the top floor.
