How to complete the Basement Generator puzzle in the Black Ops 6 campaign
To activate the generator in the basement, you'll need to interact with specific handles in the correct sequence. Follow these steps to complete the challenge:

- Adjust Fuel Valve on your left after that and set it to 50.
- Then, go to the Pilot valve on the right, and turn it on.

If no further interaction options are available, you have successfully completed the puzzle.
How to complete the Piano puzzle in the Black Ops 6 campaign
To complete the Piano puzzle, first, head to the room where the piano is located. Look for a blacklight next to the fireplace, which will help reveal hidden messages on the walls and other objects.

The first pattern will appear above the piano, while the other patterns are scattered across different areas within the same room. These patterns follow a number-letter format: 1Mn, 2Pe, 3Cn, 4Ao, 5Pe.
They remain the same for everyone. After identifying all the patterns, interact with the piano and play the keys corresponding to the letter patterns in the following order: Mn, Pe, Cn, Ao, Pe.

How to complete the Basement Keypad puzzle in the Black Ops 6 campaign
After solving the Piano puzzle to unlock the hidden door, head down to the basement and follow the hallway until you reach a four-way intersection. Turn right, where you'll find a locked door requiring a five-digit code.
When you access the keypad, use the blacklight to reveal smudged fingerprints on the keys - these indicate which numbers have been pressed frequently.

To solve the puzzle:
- Press the numbers indicated by the fingerprints.
- Even if you enter the correct numbers in the wrong sequence, they will still be recorded.
- If a digit is placed in the correct position, it will be marked as Correct. However, if a digit is valid but in the wrong position, it will be marked as Wrong Location.
- However, if you enter an incorrect digit, it will show as Not Used.
Use some trial and error to determine the correct sequence. Once all the digits are placed correctly, the door will unlock.

In the next room unlocked by completing the Basement Keypad puzzle, you’ll find a computer you can interact with to solve a simple puzzle. The bottom of the screen will display characters with corresponding codes.

To complete the puzzle, match the given numbers with the respective letters to form the four code words.
How to complete the Lockpicking puzzle in the Black Ops 6 campaign
After completing the Computer Hack puzzle, one of the doors in the basement will unlock. To reach this door, return to the four-way intersection, turn right, and follow the path until you find an unlocked door on the left.

Enter the room, and you will see a locked door directly in front of you that requires you to lockpick it. The Lockpicking puzzle is straightforward: rotate the lock pick until all three pins rise and the door will be unlocked.

How to complete the Radio Room puzzle in the Black Ops 6 campaign
To complete the Radio Room puzzle, first collect the key (from the room you lockpicked into earlier) and return to the four-way intersection. Turn right and proceed straight ahead. At the end of the hallway, you’ll find a locked door on your left that can be unlocked with the key.

Inside the room, directly ahead on a bookshelf, you will find a radio. Tune the radio signal by matching the amplitude wave with the frequency wave, adjusting both until they align. It’s recommended to turn on your subtitles, as the message that plays after completing the radio signal puzzle is crucial for opening the safe.
A Russian voice will recite two sentences. Pay attention to certain keywords in these sentences. As you explore the room, you’ll discover various items; using your blacklight, you can uncover hidden numbers on them. Listen carefully to the radio voice and note the keywords.
For example, if the sentence includes words like "chalkboard", "curtain", "rug", and others, move near these items and use the blacklight to reveal the corresponding hidden numbers.
The sentences will contain four keywords that represent items in the room. Once the words are spoken, sequence the numbers in the order of the keywords.
