Here’s a guide on how to unlock the secret areas in Call of Duty: Black Ops 6’s campaign, solving the puzzles and finding the basement doors, specifically under the KGB safehouse.

How to Open the Basement Doors in Black Ops 6

Solve the Piano Puzzle:
- To access the hidden basement, start with the piano puzzle in the safehouse. This puzzle requires you to play the keys in a specific order, which is Mi, Re, Ti, Do, Re. Once solved, the secret door to the basement will open, revealing access to a hidden area under the safehouse.
Complete the Boiler Room Puzzle:
- Another basement door leads to the boiler room. Head to the narrow hallway adjoining the main hub room and follow it down to the basement area. To start the boiler puzzle, adjust the controls:
  - Turn the Fuel wheel twice, the Boiler wheel twice, then turn the Fuel to half and flip the Pilot switch. Finish by setting the Boiler to full. This sequence activates the boiler, granting access to the boiler room beneath the safehouse.
Other Safehouse Puzzles (Optional for Extra Rewards):
- Additional puzzles scattered around the safehouse yield rewards and achievements. These include a keypad puzzle that opens a holding room (look for clues using a blacklight to find fingerprint patterns on the keypad), a lockpicking challenge to obtain a basement key, and a radio tuning puzzle. For the radio, align the amplitude and frequency dials until the waveforms match up. Completing these puzzles can earn you the "The Puzzles, Mason" achievement, along with in-game currency and other unique items.

By cracking the basement puzzles in Black Ops 6, you’ll unlock hidden areas, pick up special rewards, and get a deeper look into the campaign’s storyline. These steps cover everything from the piano keys to the boiler controls, helping you navigate each puzzle and uncover the secrets under the safehouse. Dive in, solve the mysteries, and see what’s waiting for you in those hidden rooms!
