Operation Chaos has a Decrypt Floppy Disk objective. This guide on How To Decrypt The Floppy Disk In Call Of Duty Black Ops: Cold War will guide you through the entire process so you can find the code and the passphrase to solve this little puzzle for yourself.
The exact code and passphrase to access and decrypt the floppy disk is likely different for different players. As such, we’re going to give you everything you need to solve the puzzle for yourself, just in case your solution was slightly different to ours. There is a requirement before you’re able to do this, you must have gathered the appropriate evidence.
How To Decrypt The Floppy Disk In Call Of Duty Black Ops: Cold War
We have a detailed evidence guide so if you’re struggling to find the appropriate evidence, be sure to check that guide out. However, this simple breakdown of where to get each piece of evidence should be enough.
- Nowhere Left To Run Mission – The first mission. At the end, don’t throw Qasim off the roof and he will give you a coded message evidence piece.
- Brick In The Wall Mission – In the room where you shoot or rescue the operative. The evidence is on the table
- Redlight, Greenlight Mission – At the end of the mission, after the first NPC attack. A room where you are attack by all the guards. A map on the wall
Once you have all three pieces of evidence, you’ve got everything you need. Once you’re back in base interact with the mission board and select the Operation Chaos mission at the top. Then select Examine Evidence.
The first piece of evidence you want to look at is the “A Coded Message” evidence. One row has a mixture of Red and Blue numbers alongside some ? icons. You need to find the missing numbers in the sequence. For example, my note above is 68 (Red) 50 (Blue) ? (Red) 54 (Blue) 74 (Red) 58 (Blue) 80 (Red) ? (Blue) 88 (Red) 66 (Blue). On my notes, the red numbers are first so I need to find the missing red number and then the missing blue number.
So, the red numbers 68, ? 74, 80, 88. I need to find the ? value. The value is 70 because it is adding 2 to the amount added each time. 68+2=70, 70+4=74, 74+6=80, 80+8=88. The blue numbers, 50, 54, 58, ?, 66 is a simple one. It’s just adding 4 each time. So the missing blue number is 62. So the final solution to this clue for me is 7062.
Now you need to examine the Numbers Station Broadcast clue. You can see here that each city has a 4 digit code associated with it. New York is 7,0,6,2, which is exactly the same as the 7062 code I had from the first clue.
Lastly, it’s time to look at the final clue, the Front Page of the Observer clue. Inspect the clue and you will see several letters are red. For mine it was R, H, N, L, S, E, O, T, C, A. Mix those letters around a bit and they spell out one of the cities in the Numbers Station clue, for me it was Charleston which is 5792.
So now I have everything I need. Go back to the Floppy Disk and select Decrypt. The code is the final clue from the newspaper, 5792, and the passphrase is the city from the first clue, so in my case, it’s New York. So finally, I enter 5792 and New York and Decrypt the Floppy Disk.
