Black Ops Cold War Operation Chaos Guide: How to Decrypt Floppy Disk

What evidence do you need for Operation Chaos?

You need the following evidence to successfully decrypt the floppy disk for Operation Chaos.

• Observer's first page (Red light, green light)
• A coded message (Capture Qasim Javadia in the first Nowhere to Run mission)
• Station broadcast numbers (Brick in the wall)

If you missed any of the evidence listed above, replay the listed mission and look for the evidence. Once you have all three, it's time to solve the puzzle.

How to decrypt the floppy disk

To start solving the puzzle, examine A coded message. Some numbers will appear and leave two question marks for you to fill in. Red numbers and blue numbers follow a defined pattern, and you should use that pattern to infer which numbers are missing. Everyone has different numbers and models, so you will have to do calculations on your side. In my case, the red numbers added 6 each time, going from 28 to 34 to 40 and so on. The blue numbers grew by a larger number each time, adding 1 to the first number, 2 to the second number, 3 to the third number, and so on. Keep in mind that the patterns and numbers will be slightly different on your end.

Once you've deduced the missing numbers, put them together to create a four-digit sequence. With that four-digit code in hand, examine the Station broadcast numbers. Find which city matches your numbers. It's the passphrase the computer will ask you later.

Then examine the Observer's first page. The title will have a random group of letters highlighted in red. It's actually a scrambled word that will give you your next clue. Then take a look at the broadcast from Numbers station. There is a list of locations, and the red scrambled letters on the watcher's home page can be rearranged into the name of any of these locations. For example, if the letters INTUSA are highlighted in red, they can be rearranged to say Austin. Each player has a different place name, so you have to do the detective work yourself.

After deciphering the name of the city, examine the Station broadcast numbers one more time. This time find the four numbers that correspond to the city name you have. These four digits are the queues the computer will ask you.

Once you've solved both puzzles, it's time to decipher the floppy disk. Select " Decrypt the floppy diskAnd enter the code and passphrase you got in the above puzzles. If done correctly, you will crack the code and get the information you need for Operation Chaos.
