Today, we’re diving into the latest Call of Duty: Black Ops 6 campaign, where I’m going to guide you through solving all the puzzles in the safe house. These puzzles aren’t just for bragging rights—they’re essential for unlocking significant rewards like a hefty cash bonus, a special melee weapon blueprint, and even an achievement or trophy. So, let’s break down each of the steps and crack the safe!

Step 1: Start in the Basement - Powering the Boiler

Our first step takes us to the basement of the safe house. Here, we’ll need to get the boiler running to unlock a crucial door later. You'll find several notes in the room that hint at the puzzle mechanics, so pay attention to those!

To start, head to the boiler control area, where there are three main components to interact with:

    Fuel Valve (left): This controls the fuel supply.

    Water Valve (middle): This controls the water flow.

    Pilot Light (right): This controls the ignition.

Follow these steps carefully:

    Turn off the water valve: This stops the water flow and is the first step to starting the boiler.

    Adjust the fuel line: Turn the fuel halfway.

    Ignite the pilot light: Go to the pilot light and interact with it. Once you turn it on, it should glow green if done correctly.

If you’ve followed these steps in order, the boiler should now be powered up. With the boiler running, it will supply power to the door you’ll need later.

Step 2: Solve the Piano Puzzle

Next, we’ll need to navigate to the main lobby area. To the left, you’ll find a piano room. On the desk next to the piano, you’ll see a black light. Interact with it (left on the D-pad) to reveal five musical notes, each associated with a letter.

The notes are numbered in the order they should be played, and while the letters may seem foreign (I believe they are in Russian), here’s a simple translation to help you:

    First note: MN (equivalent to 'M' in English)

    Second note: P

    Third note: CN

    Fourth note: AO

    Fifth note: PE

Using your black light, locate these notes around the room, and then play them in the correct order. Once you’ve played them all in the right sequence, the door next to the piano should open.

Step 3: Decode the Keypad Puzzle

Now that the door has opened, you'll enter a hallway with several locked doors. The first thing to do is take a right turn, where you’ll find a keypad on the wall to the right of a door. This is similar to a game like Wordle—you need to use your black light to find the most frequently used numbers.

Here's how it works:

    Enter a number.

    If it's green, the number is in the correct position.

    If it's yellow, the number is in the code but not in the right spot.

    If it's red, the number isn’t part of the code.

Start experimenting with different combinations and try to narrow down the correct numbers. If you make a mistake, the game will reset and give you a new series of numbers to solve.

Once you’ve cracked the code, the door will open. Time to move on!

Step 4: Solve the Cipher on the Computer

After entering the next room, you’ll find a computer at the end of the hall. This one’s pretty straightforward, as it’s a cipher puzzle.

Look for the code word displayed as a series of numbers at the top of the screen. For example, you might see “862 915.” Below that, there’s a cipher key that corresponds numbers to letters.

Here’s how to decode it:

    8 corresponds to the letter B.

    6 corresponds to U.

    2 corresponds to N.

And so on until you’ve decoded all the numbers into a word. For me, the four words were bunker, open, room, and holding.

Enter these words into the computer, and the door to the next area will unlock!

Step 5: Lockpick and Grab the Key

You’re making great progress, but there’s one more thing to do before we get to the safe. In the hallway, there’s another locked door. You’ll need to use your lockpicking skills to get through.

This is a simple mini-game: use the right stick to move and lock the pins in place. Once the door opens, enter and grab the key from the desk. Now you’ve got what you need to continue.

Step 6: Tuning the Radio and Listening for Clues

Now it’s time for another puzzle. Take a right at the intersection, and you’ll find another locked door. Use the key to open it, and inside, you’ll find a radio signal. To interact with it, you need to adjust the amplitude (wave height) and frequency (how often those waves occur) to match the signal on the radio.

Once the signal is tuned correctly, you'll hear a transmission. Pay close attention, as this is where the puzzle gets a little tricky. You’ll need to identify four items that are mentioned in the transmission and that can be found in the room with you.

For me, the items were:

    Ashtray (8)

    Ancestral Crest (9)

    Couch (3)

    Chair (5)

Write down these numbers in the order mentioned. If you’re having trouble with one of the items, you can use a bit of trial and error to find the correct number for the last item.

Step 7: Crack the Safe

With the numbers from the radio puzzle, head upstairs to the bedroom where the safe is located. Interact with the safe, and enter the numbers you obtained: 8935.

If the code is entered correctly, the safe will open. Inside, you’ll receive 1,000 bucks, which you can use to upgrade your safe house. And that’s not all! You’ll also unlock the Case Cracker Melee Weapon Blueprint, which is a pretty sweet bonus.

Step 8: Upgrade Your Safe House

Now that you’ve cracked the safe, you can use your earnings to upgrade your base of operations. Upgrading your safe house is crucial, as it allows you to purchase various perks for the campaign, enhancing your abilities and making the next parts of the story that much more exciting.

Conclusion

And there you have it! You’ve solved all the puzzles in the safe house, cracked the safe, and earned some valuable rewards. These steps not only unlock essential items for your campaign but also grant you an achievement or trophy—always a nice touch.
