Decrypting the Floppy Disk for Black Ops Cold War campaign’s Operation Chaos may seem confusing, but we’ve broken it down into easy to follow steps.

As well as all the game’s different endings and unlockable ZORK terminal & Arcade, Call of Duty: Black Ops Cold War’s campaign has several side-missions for you to complete as you progress.

After completing the mission ‘Fracture Jaw,’ you’ll have access to the Evidence Board. From this board, you can replay missions, look over the evidence, and take part in side-missions. One of the first you’ll unlock is ‘Operation Chaos’ which tasks you with decrypting a floppy disk containing information about a Spy Ring you need to shut down.

You’ll need to find evidence in campaign missions, and then know how to solve the code to decrypt the floppy disk.

Here’s how to find the clues and solve the puzzle for Black Ops Cold War’s Operation Chaos mission.

Where to find Cold War’s Operation Chaos evidence

In the mission ‘Brick in the Wall,’ a side mission has you talk to Greta, an informant. Inside the bar, approach and talk to her, and she’ll ask you to either rescue or kill a man named Richter.

After freeing, or killing, Richter, you’ll be able to pick up evidence from the table in the center of the room.

Complete the mission then advance on to the next mission: ‘Redlight, Greenlight.’

When this mission takes you to the replica U.S town, go to the end of the street then to the top floor of the last building. You’ll find a map on the wall marked as evidence, so follow the game’s prompt to take a picture of it.

You now have everything you need to decrypt the floppy disk. Finish ‘Echoes of a Cold War’ then you’ll be able to access to Evidence Board again.

How to decrypt the Operation Chaos floppy disk in Black Ops Cold War

After accessing the Evidence Board, click on ‘Operation Chaos’ and select ‘Examine Evidence.’

A Coded Message

To decipher the coded message, you need to spot the pattern in a series of numbers.

This is where it gets a little confusing. Unfortunately, every single player will have a different number pattern to decipher, it’s completely random. We can’t tell you exactly how to do yours, but we can explain our logic to help you.

black ops cold war number pattern

Our sheet has 5, ??, 12, 14, 15 in red writing. Counting backward, the difference between 15 and 14 is 1, and 14 and 12 is 2.

The pattern appears to be adding one less number each time, so take away three, the next lowest number, away from 12 and you’ll have 9. Take away 4 from 9 and you’ll have 5, showing that 9 is the missing number.

Our page also had 7, 12, 17, ??, 27 in blue letters. The difference between all of these numbers is 5, so 17+5=22. You can double-check by adding another 5 onto 22 which equals 27. Therefore 22 is the missing number.

So the answer to our Coded Message is 0922.

The Front Page

Luckily, decrypting the Front Page is much easier than the Coded Message.

On the headline of the newspaper, you’ll find certain letters are marked in red. Write down these letters, then take a look at the Numbers Station Broadcast list.

The red letters can be rearranged to spell out one of the cities on the list. For example, if your red letters are A H M O A, they can be rearranged to spell ‘Omaha.’ Check the number code beside the city and write those down.

Decrypt the Floppy Disk

Now, find the full number you discovered from the Coded Message and find the city it corresponds to, and write down the city name.

Now, you’re ready to decrypt the floppy disk.

  1. Go back to the ‘Operation Chaos’ menu and click ‘Decrypt Floppy Disk.’
  2. Enter the code that matched the city discovered from The Front Page
  3. Enter the city name The Coded Message corresponds to

The floppy disk will now be decrypted, so you can launch the Operation Chaos mission with all of the intel you need.

Hopefully, that’s cleared a lot of it up for you, and it’s a nice touch to have something a bit out of the norm for a Call of Duty game to vary things up.

Once you’re done with the Black Ops Cold War campaign, we have plenty of guides on the Die Maschine, Firebase Z, and Outbreak Zombies content. We also have tons of guides covering Cold War’s multiplayer too, including a ranking of all the game’s maps and best guns.

Best UGR loadout for Black Ops Cold War

The UGR is a brand-new SMG in Black Ops Cold War, so here’s our best compelte with Attachments, Perks, and Equipment.

Best UGR loadout in UGR

The UGR is a brand-new SMG in Black Ops Cold War, and players can’t wait to try it out in multiplayer matches. Here’s our breakdown of the best UGR loadout to run in BOCW.

Even though CoD Vanguard is now in its third season, and Modern Warfare 2 is arriving this year, support for Black Ops Cold War is still going strong. After a huge Zombies patch on April 25, Treyarch have now added a remastered version of the Jungle map, as well as a new weapon.

The UGR SMG is an interesting close-range option, as it’s an “underwater rifle modified for improved land performance.” It doesn’t have the bullet velocity to take enemies out at distance, but it’s formidable in close-quarters combat.

If you’re looking to run it in multiplayer, you’ll need to know how to make the most of it. Check out our best UGR loadout for Black Ops Cold War.

Best Cold War UGR loadout attachments

Operator underwater using UGR
  • Barrel: 12.8″ VDV Reinforced
  • Underbarrel: Spetsnaz Grip
  • Magazine: Explosive Flechettes
  • Handle: GRU Elastic Wrap
  • Stock: KGB Skeletal Stock

We kick things off with the 12.8″ VDV Reinforced Barrel to seriously boost the UGR’s bullet velocity and damage range. The UGR is severely lacking in both departments, but this attachment makes it far more competitive in longer-range battles.

Next up, we went for the Spetsnaz Grip to keep the recoil in check and make it far easier to control. Then we chose KGB Skeletal Stock and GRU Elastic Wrap for a decrease in sprint-to-fire time and ADS speed, allowing you to get shots earlier while rushing around the map.

Many were surprised to see that the UGR comes with explosive rounds, so we couldn’t resist equipping Explosive Flechettes to our loadout. Aside from the obvious boost in overall damage, they also increase ammo capacity which is vital in a fast-firing weapon.

Best Cold War UGR Perk & Equipment

Flak Jacket Perk in BOCW
  • Perk 1: Flak Jacket & Tactical Mask
  • Perk 2: Scavenger & Assassin
  • Perk 3: Ghost & Ninja
  • Lethal Equipment: Semtex
  • Tactical Equipment: Stimshot

We think the UGR is still effective with only five attachments, so we’re equipping Greed Wildcard to use extra Perks in each slot in BOCW multiplayer matches,

Flak Jacket and Tactical Mask are incredibly important in the first slot, as they’ll keep you protected from incoming explosives and Gas Mines, which can be frustrating when running and gunning.

Next, we picked Scavenger to make sure you never run out of ammo, as well as Assassin to keep the Scorestreaks rolling in. In the final slot, we recommend Ghost to stay invisible on enemy radars, as well as Ninja to help with flanking, which you’ll want to do a lot of with the UGR.

In terms of equipment, Semtex is an easy-to-use lethal, while Stimshot will give you a handy health boost when things get tough out there.

How to unlock UGR in Black Ops Cold War

UGR in Warzone

To unlock the UGR SMG, players must kill an enemy revealed by their Spy Plane, UAV, or Field Mic with an SMG in 15 different completed matches. If you’re not a big multiplayer fan, it can be earned in Zombies by eliminating 1000 enemies while using an Epic rarity or better SMG.

You can also bypass the challenges altogether if you don’t mind spending 2,400 CoD Points on the new Lazar bundle.

Best alternatives to Cold War’s UGR

Black Ops Cold War has some powerful SMGs if the UGR isn’t working for you. The TEC-9 and LC10, in particular, remain incredibly strong in multiplayer matches and rank as two of the best weapons in the entire game.

UGR unlock Warzone cold war

Treyarch continue to release new weapons for Cold War and the latest is the UGR SMG based on the APS underwater rifle that will be making its way to both Cold War and Warzone. Here’s how to unlock the UGR in Cold War and Warzone.

Although Vanguard is now in Season 3 and 2022’s Modern Warfare 2 has been announced, Treyarch are still releasing content for 2020’s Black Ops Cold War. Alongside a ton of Zombies changes that arrived with the April 25 update, Treyarch confirmed the classic Jungle map and a brand-new weapon would arrive in the “coming weeks.”

On May 6, the new UGR SMG made its way to the game alongside a remastered version of the Jungle map. Here’s how to unlock the UGR in Cold War and Warzone.

UGR SMG in Cold War & Warzone

Those who played Call of Duty: Ghosts may recognize Cold War’s new UGR SMG as it’s based on the APS underwater rifle that appeared in the campaign. The in-game description says it’s a “full-auto submachine gun” and an “underwater rifle modified for improved land performance.”

The weapon is projectile-based with quite a low bullet velocity, so you won’t be beaming enemies at range with ease. Players were also surprised to see that it comes with explosive bullets.

How to unlock UGR in Cold War & Warzone

Players can unlock the UGR by killing an enemy revealed by your Spy Plane, UAV, or Field Mic with an SMG in 15 different completed matches. You can also unlock the UGR in Zombies if you eliminate 1000 enemies while using an Epic rarity or better SMG.

The new UGR SMG has the same unlock challenge for both Cold War and Warzone, so it’ll be up to you to decide which game you’d like to complete it in. In addition, you can also receive the UGR straight away by purchasing the new Lazar bundle for 2,400 CoD Points.


The Nikita AVT and M1916 have also arrived in Warzone with Season 3, so you can check out how to unlock the new Assault Rifle and Marksman Rifle.

Treyarch confirm Jungle map remaster & new weapon arriving in Black Ops Cold War

Black Ops Cold War devs Treyarch have confirmed a new long-range weapon and Jungle map remaster coming soon.

Treyarch have confirmed brand-new content is on the way for Black Ops Cold War, including a new weapon and remastered version of the classic Jungle map.

While Black Ops Cold War’s seasons have ended, the Call of Duty title received additional content through an update in March, including the arrival of the WMD map and the Vargo 52 Assault Rifle.

Now, Treyarch have announced more new additions that they have planned for Black Ops Cold War in May and beyond, including a long-range weapon and a remastered version of a classic Call of Duty map.

Cold War Jungle map remaster release date

Treyarch confirmed that the remastered Jungle map will make its way to Black Ops Cold War on Friday, May 6. The new map hit the game at 10:00 AM PT / 1:00 PM ET / 6:00 PM UK.

Treyarch originally confirmed their plans for brand-new Call of Duty content in a blog post on April 14, including the addition of the classic map Jungle. When the map hits the game on May 6, players will be able to jump into a Jungle 24/7 playlist.

When this map first made its debut, it consisted of a ruined village and military base near a river in the middle of a Vietnamese jungle. Players could take advantage of its many slopes and ladders to move quickly between levels.

Jungle won over players with its impressive layout and was added to other CoD titles like Black Ops III and Black Ops 4. Now, a remastered version will be added to Cold War’s standard 6v6 playlists in a new update.

Treyarch also teased the arrival of an “all-new ranged weapon” that players will be able to use in both Black Ops Cold War and Warzone. This new weapon arrived alongside Jungle on May 6.

Adding new weapons often shakes up the meta of CoD titles, so we can expect major changes after this new content drop arrives.
