How to build the RAI K-84 in Firebase Z – Black Ops Cold War Zombies

Here’s how you can craft yourself a RAI K-84 wonder weapon in the brand new Firebase Z map for Black Ops Cold War Zombies!



Here’s how to build the RAI K-84 wonder weapon in Black Ops Cold War’s newest Zombies map, Firebase Z.

The RAI K-84 is the wonder weapon of Firebase Z, and by far is the toughest buildable in Black Ops Cold War Zombies. Here’s how you can build one yourself. For today’s tutorial, we’ll be following YouTuber MrRoflWaffles guide.

Note: Follow all steps in order, or you may get stuck.

Step 1 – Grab The Blueprint

To the left of the computer in the weapons lab will be on the wall on top of a weapons bench.

Step 2 – Retrieve The Eye

In the Scorched Defense area, or the beach, there will be a corpse leaning against a tank. Interact with it to take its eye.

Step 3 – Scan The Eye

Double back to the weapons lab and interact with the computer. The eye will be scanned and the desk drawer will open, revealing a locker key.

Step 4 – Open Lockers

In the barracks area, we’ll be opening lockers with the key we found in step #3. There are lockers in both barracks 1 and 2, so keep this in mind. As you open the lockers, you’ll want to find one that spawns a mimic.

Kill the mimic and see if it drops a “Barrel Stabilizer”. If it doesn’t, simply try again with the other lockers. This may take several tries.

Step 5 – Uncharged Power Cell

After round 15, the Mangler boss zombies will begin to spawn. We will need an uncharged power cell that is randomly dropped. Keep killing Manglers until you locate one.

Step 6 – Charging The Power Cell

Go back to the weapons lab and locate the table next to the armor upgrade station. Here you will be able to place a power cell to charge. Leave this here and go kill some zombies. It may take a full round to charge.

Step 7 – The Dart Board

This is by far the most frustrating step of all. If you get stuck, we recommend referencing MrRoflWaffles YouTube video for more visual aids.

For this step, you’ll be interacting with the computer in the Weapon Lab. There will be a light that goes in a circle and freezes a total of three times. Each freeze will correspond to a position on a dart board in the spawn room. Memorize these positions, then go to spawn and shoot the board in each position the computer noted, then shoot the bullseye.

If done correctly, the Aethurium Converter piece will drop.

Step 8 – Build the RAI K-84

We’ll be going back to the Weapon Lab for the final time now, where you can build the RAI K-84 on the workbench from step 1.

That’s it! If you ever get stuck, remember to watch MrRoflWaffles video, linked below.

How to use the RAI K-84 & Ray Gun together in Cold War Outbreak

Cold War’s Outbreak allows players to carry either the RAI K-84 or the Ray Gun, but with this clever trick, you can use both at once.

For maximum firepower, you’ll want to carry a Wonder Weapon in Black Ops Cold War’s Outbreak. With this clever trick, you’ll be able to carry both the RAI K-84 and Ray Gun at once.

Black Ops Cold War has introduced new toys for Zombies players to slay the undead with, the D.I.E Shockwave and the RAI K-84, as well as brought back the classic Ray Gun.

Black Ops Cold War’s latest Zombies mode, Outbreak, allows you to get your hands on all three Wonder Weapons. Unfortunately, you can only carry either the Ray Gun or RAI K-84. With both of these weapons in your hands, Zombies wouldn’t stand a chance.

However, with some skilled timing and the know-how, you can carry two Wonder Weapons at the same time and be an unstoppable force in Outbreak.

How to carry two Wonder Weapons in Cold War’s Outbreak

Reddit user Retr0virus11 created an in-depth guide on how to hold the RAI K-84 and Ray Gun at the same time in Outbreak.

Before beginning, you need to have one of the two weapons in your inventory, and we’ve put together a guide on how to get each Wonder Weapon in Outbreak.

To summarize our clever Redditor’s guide:

  1. Get your hands on either a Ray Gun or RAI K-84.
  2. Make sure neither of your weapons has been Pack-a-Punched.
  3. Hold out the Wonder Weapon and swap it as you interact with the Pack-a-Punch, then buy an upgrade, and the weapon will be duplicated.
  4. Find the other Wonder Weapon that you don’t have.
  5. Simply pick it up, and you’ll have both weapons at once!

This trick also works if you want to rock double Ray Guns or RAI K-84’s so you can wield maximum firepower while fighting hordes of the undead in the Ural Mountains.

While carrying these two powerful Wonder Weapons, you can also check out our guides on how to get free perks and complete the Dragon Easter Egg in Cold War Season 2’s Outbreak.

When are Black Ops Cold War Zombies camos coming to Warzone?

Black Ops Cold War fans have been desperate for Zombies weapon camos to come to Warzone, so when will they be arriving?



Warzone Plague Diamond camo

Weapon camos unlocked in Black Ops Cold War Zombies aren’t available to use in Warzone, but with Zombies arriving in Verdansk, and the camos found in the game files, they’ll likely arrive during Season 2.

Warzone Season 2 has continued and expanded Warzone’s integration with Black Ops Cold War, adding new weapons the FARA 83 and LC10, as well as bringing Zombies across to the game. However, a plethora of Zombies personalization content still hasn’t been included, but a recent leak reveals they may be coming during Season 2.

When Black Ops Cold War first integrated with Warzone in December 2020, fans who had grinded for the Cold War Zombies Mastery Camos, Golden Viper, Plague Diamond, and Dark Aether, were disappointed that they weren’t available in Warzone.

BOCW Dark Aether camo

Activision acknowledged this omission, saying that “Zombies Calling Cards, weapon camos, reticles, and Onslaught Blueprints,” would not be available at the start of Season 1. In Season 2, these still aren’t available to players but have reportedly been found in the game files.

Call of Duty leaker ZestyCODLeaks tweeted on March 5 that “all of the BOCW Zombies camos are in Warzone, including Mastery Camos like Plague Diamond & Dark Aether.”

We already knew from Activision that these camos will be coming eventually, but with a data miner reportedly finding them in the game files, it’s highly possible they will arrive in Season 2.

When are Zombies camos available in Warzone?

“I don’t know when [Zombies camos] are coming, but likely soon due to fan requests,” said ZestyCODLeaks on March 5.

With Zombies now in Verdansk, and the contagion beginning to spread, it’s possible that these camos will arrive with the Outbreak Event’s conclusion on March 11. This date also marks the one-year anniversary of Warzone, which is when the leaked Plague game mode, in which Verdansk will be nuked, is expected to take place.

CoD Warzone Zombies

After Verdansk is nuked, it’s all-but-confirmed that Warzone will head to the Ural Mountains, which is also where the latest Zombies mode, Outbreak, takes place. When Warzone makes the full shift to a Black Ops Cold War map, this would be the perfect time to bring more Cold War content to the game, including Zombies camos, reticles, and calling cards.

Warzone Season 2 is heavily focused on Zombies, so expect more Zombies content to be added over the course of the season.
