Operation Chaos & Operation Red Circus Complete Guides (Black Ops Cold War Side Missions)

Once you've collected all the evidence, we can proceed with Operation Chaos floppy disk decryption and, finally, the mission itself. To decrypt the floppy disk, we need a code and a passphrase that we can get by using the pieces of evidence that we've collected from various missions.

First, open up the newspaper and you will notice that some of the letters on the newspaper headline are highlighted in red. These letters are an anagram for one of the cities in the Numbers Station Broadcast which we will come to in a bit.

The highlighted letters for us were ATATLAN, which spells the city ATLANTA. Note that the city names, numbers, and all the content used to solve is completely random and unique for every player, but the method to solve is the same.

Once you've identified the city's name, open up the Numbers Station Broadcast and check the numbers corresponding to that city. As you can see from the image below, Atlanta has the numbers 0,1,8,6.

0186 is your passcode.

To get the passphrase, we will do the opposite. We will use the coded message from Qasim Javadi to identify the numbers and convert them into a city instead.

As you can see in the picture above. There is a sequence of numbers in both blue and red, with some missing (written as "?"). We need to find the missing numbers and find the corresponding city.

First, write the red and blue numbers separately.

Red

: ?, 09, 15, 21, 27

Blue

: 63, ?, 69, 75, 83

The second step is to find the pattern in these numbers. Find a pattern that the numbers follow and accordingly find the missing number following the same pattern. Note that the pattern will be completely different for all the players. So, you must find your pattern. Here's an example of what our pattern looked like to give you an idea of how to approach the problem.

If we only look at the red sequence, you will notice that each number has a difference of 6. If you subtract 21 from 27, you get (-)6. If you subtract 15 from 21, you get (-)6 again. That means whatever the missing number is, it must be a product of 6 subtracted from 9. You get 3. So the missing red number is 03.

For the blue sequence, if you subtract 75 from 83, you get (-)8. If you subtract 69 from 75, you get (-)6. If you notice, the difference isn't consistent like our red sequence, where the difference of 6 was consistent throughout the sequence. Here the difference is decreasing by 2 every time we move from right to left in the sequence.

To ensure we get the far left number as 63, we must follow the same pattern of decreasing the difference by 2 every time. We will get our missing number, which is 65, by subtracting 4 from 69.

And to confirm this pattern's authenticity, we can subtract 2 from 65 to get 63, which is the first number in the sequence.

So our two missing numbers are 0365. Open the Numbers Station Broadcast once again and check which city corresponds to the number 0365. For us, it was Omaha.

Omaha is your passphrase.

Now that you have the code (0186) and your passphrase (Omaha), you can enter it in the terminal to decrypt the floppy disk. Click on the floppy disk to access the computer terminal.

First, you will be asked to put in the code, which is 0186.

Then the passphrase, which is Omaha for us. Make sure all the letters are lower-case as these are case-sensitive. Some people have trouble with this, and they get confused.

After entering the correct credentials, you will get an "Access Granted" message, indicating the successful description of the floppy disk.

You can now proceed with the main Operation Chaos mission, where you must go through the mission to reach Aldrich, eliminate him, and take a photo of the dead body as confirmation.

Operation Red Circus is the second side mission, which is available after the mission 'Fracture Jaw.' You can either launch the mission right after it appears on the evidence board or wait until the completion of the mission 'Desperate Measures,' after which you would have collected all the needed evidence to identify the three correct suspects working under Soviet Major Vadim Rudnik.

Vadim Rudnik is helping Perseus place Soviet agents all over Europe. If you start the mission without identifying the agents, it won't be a 100% completion. You must identify the three agents before killing Vadim Rudnik.

Just like Operation Chaos, Operation Red Circus also requires collecting some evidence that will help you find the three key agents. There are three pieces of evidence spread across three different missions.

Now that we've collected the evidence, we are ready to identify the suspects and mark them. We will start with the wristwatch.

The wristwatch helps us identify the locations where the possible targets must have visited. The three targets are dubbed as the "Bearded Lady," "Strong Man," and the "Juggler."

From the wristwatch dead drop list, we can identify the locations these three suspects have visited and the date they visited these locations on. For easier understanding, let's draw up a table and start filling in the information as we gather it.

We can use the cassette tape to identify our suspects' genders, in order to narrow down our list of suspects.

In the image above, you can see how the three suspects are referred to as either "He" or "She" this helps us identify their gender. This means that the Bearded Lady and Strong Man are both males while the Juggler is a female.

Finally, we come to the ledger. This ledger contains the list of money paid to these three suspects and the locations where they were paid at. This gives us another set of locations with dates. You might be wondering why we need more locations? Some of the targets visited the same location, so we need more locations to cross-check and confirm.

According to Kraus's ledger, the bearded lady was paid $15,000 in Dijon, France on 09/04/80, The Strong Man was paid $7,000 in Vienna, Austria on 01/08/81, and the Juggler was paid $12,000 in Copenhagen, Denmark on 12/04/80.

We now have all the needed information to start marking the targets from the "Review Suspects" menu.

Our first target would be Alex Superty. He matches the complete profile of the "Bearded Lady." He is a male suspect, just as we established from the cassette tape. His recent travel list includes visiting Krakow, Poland on 10/04/80 and Dijon, France on 09/04/80.

The second target would be Aaron Lee, who matches the "Strong Man" profile. The Strong Man is a male just like Aaron Lee, who visited Paris, France on 01/21/81, and Vienna, Austria on 01/08/81.

The final confirmed suspect is a female. For this one, we can ignore all the other male suspects and focus on the three female suspects. The only female suspect who matches the exact profile of the "Juggler" is Claire Koberstein. Her recent travel list includes visiting Rome, Italy on 01/09/81, and Copenhagen, Denmark on 12/04/80.

Our final table looks like this. Remember, your suspects can be completely different based on the information you get from your pieces of evidence.

After identifying all the targets and marking them, you can proceed with the main Operation Red Circus mission to find and eliminate Soviet Major Vadim Rudnik.

Remember to take a picture of the body for confirmation.

And that's how you complete both the side missions. Note that after a certain point in the campaign, you won't be able to access these missions, specifically after the Cuba Briefing. Once you start the mission 'End of the Line,' you won't have access to the evidence board from that point onward. So make sure you complete both the operations before that.
