How to Decrypt the Floppy Disk Code in CoD Black Ops Cold War

Call of Duty: Black Ops Cold War is officially live, so naturally it’s time to shoot a bunch of guns, blowing everything up, and embrace your 80s militaristic power fantasies. Taking the Call of Duty experience to next-gen, this entry includes a new campaign, multiplayer, weapons, maps, gadgets, killstreaks, and zombie maps for players to enjoy. Warzone also makes a return, fusing with Modern Warfares so all your progress, characters, and weapons carry over. Unlike previous games, there’s a heavier emphasis on obtaining all the collectibles and reading the various bits of lore scattered throughout. Not only will this deepen the rather thin plot, but it will unlock new optional missions for you to complete.

However, before you can embark on Operation Chaos, you will need to first find three key pieces of evidence and then decrypt several codes from the intel you’ve collected. This can be pretty tricky since everyone’s code is different, so we will walk you through what to look for when solving each of them.

Decrypting the Floppy Disk

Black Ops Cold War Passphrase

The Passphrase

To decrypt the passphrase, you will need to start with the grid of numbers in red and blue. To start, all of the jargon and symbols on the paper do not matter at all. Ignore them completely, we only care about the row of numbers and the two ? spaces. When you start, break the blue and red numbers into separate groups, their correlation with one another doesn’t matter. So in the picture above, for the blue question mark space, we only need the numbers 72, 78, 81, and 84 to figure out what’s missing. Now that we have those numbers isolated, look for a pattern between the ones available. We can see that each blue number is ascending by adding three. Using this info, we can determine that the blue question mark section is 75Do this for the red question mark space as well to get both missing numbers.

Now that we have both the missing blue and red numbers, go to the Numbers Station and find the city with your missing numbers in their order. So for mine, I am picking Miami since my red number was 68 and my blue number was 75. This city will be your passphrase. Since everyone’s codes are unique, my biggest piece of advice is to not overthink it. These are pretty easy patterns to solve once you isolate the two different colored number groups.

The Code

The section portion of this puzzle is way easier. Once you have the passphrase, go to the newspaper and look at the letters that are highlighted. These letters will spell out one of the cities listed on the Numbers Station Broadcast. Mine spelled out New York, so all I had to do was find this city and then remember the four numbers tied to it. Those four numbers will be your floppy disk’s code. The other stations don’t matter, along with anything else in the newspaper article you’re given.

So now just decrypt the floppy disk by putting in your unique code and passphrase to gain access to the new mission, Operation Chaos.

    That being said this still ain’t working for me. Am I doing something wrong?

    1. Your missing Red and Blue numbers should correspond to a city in the Numbers Station. That city is your passphrase and the Charleston numbers are the code

  3. Can anyone help me with my code please

  4. I need some help with the floppy disk code I’ve been trying for hours to solve it the red is 43 ? 49 55 63 the blue is 57 ? 69 75 81

    1. Hey! Okay, so your first number goes up by two each one. So the Red number you’re missing is 45. The blue ones go up by 6, so that missing number is 63. Together it’s 45-63!

        1. 0103 isn’t going to be the number code you put it. Take that number and find the city that corresponds to your Numbers Station. That will be the passphrase. You get the code form whatever number sequence is tied to the city in the jumped newspaper.
