Call of Duty: Black Ops - Cold War - How to Decrypt a Floppy Disk

At the heart of Operation Chaos in Call of Duty: Black Ops - Cold War is a mystery that fans must solve in order to decipher the floppy disk.

To complete the Operation Chaos side mission in Call of Duty: Black Ops - Cold War, players must decrypt the floppy disk. To do this, fans must first receive a code and passphrase, which they receive after decrypting three pieces of evidence. While this multi-part process may seem rather confusing at first, players who refer to the instructions in this guide should have no problem figuring out the required code and passphrase and decoding the floppy disk in Call of Duty: Black Ops - Cold War. ...

To get started, players need to make sure they get three proofs in Call of Duty: Black Ops - Cold War. That evidence is the observer's title page, the coded message and the broadcast of the digital station, and here are the details of the Black Ops - Cold War missions from which they emanate:

• Observer Page 1: Upstairs in the bar in mission Red Light, Green Light;

• Coded message: issued at the end of the mission "Nowhere to run";

• Broadcast station numbers: on the table in the warehouse in the mission "Brick in the Wall".

With three pieces of evidence in hand, players should examine the observer's cover page and write down the red letters. They then have to study the Numbers Station broadcast and work to rearrange the letters written from the Observer's cover page to match one of the cities listed. When this is done, Call of Duty: Black Ops - Cold War players should write down the numbers corresponding to the city as they will serve as the decryption code for the floppy disk.

Now fans should study the encoded message, paying particular attention to the row of blue and red numbers. The player's job is to recognize the patterns that are established by these numbers, and then use these patterns to figure out which numbers should replace the question marks. These patterns can be something like red numbers increasing by six and blue numbers increasing by one, two, three and four, and fans should write down cryptic numbers as they solve this puzzle in Black Ops - Cold War.

Players must now go back to the Numbers Station broadcast and find the city name corresponding to the cryptic numbers. This city name will be used as the password in the Operation Chaos side mission of Call of Duty: Black Ops - Cold War, and fans now have everything they need to decrypt the floppy disk. So all that's left to do is select "decrypt floppy" and then enter the code that was hidden on the Observer's main page and the passphrase that was hidden in the encoded message.
