There are three pieces of evidence you need if you want to do Operation Chaos the right way.

In this guide, we’re going to cover everything you need to know about Operation Chaos, including where to find all three pieces of evidence, how to solve the puzzle and how to decrypt the floppy disk. There are two side missions in Black Ops Cold War: Operation Chaos, and Red Circus. You can mainline it as you would any other Call of Duty campaign, but if you take your time to look around, talk to your teammates and read the evidence you come across, there’s plenty hiding in Black Ops Cold War that is well worth your time to explore.Ĭase in point: side missions. This will complete the quest of Operation Chaos.The single-player campaign in Call of Duty: Black Ops Cold War experiments with a number of new mechanics, twists, and ideas and introduces a unique mission structure to Call of Duty. Now, put these two together to get to code to decrypt the disc. Fixing it will reveal another cities location. Now, look at the Observer clue to find a scrambled message on the front cover. This will reveal the name of the city that is the passphrase. With the coded message, red and blue numbers will appear so sort out the missing numbers and put them together. For starters, the player will need the passphrase. Now that you have all the evidence, all that is left to decrypt the floppy disc.
