How to Get a Free Wonder Weapon – Firebase Z Cold War Zombies

The R.A.I. K-84 is the brand new wonder weapon in Firebase Z and there's a way to get it for free.

Just like most wonder weapons in Call of Duty Zombies, there is a quest you can complete to earn the wonder weapon.

This article will teach you how to get the R.A.I. K-84 for free on Firebase Z.

How To Get A Free Wonder Weapon in Firebase Z

To get a free wonder weapon (R.A.I K-84) in Firebase Z Black Ops Cold War Zombies, you must collect the following items and follow the instructions.

1. Weapon Blueprint

The first thing you need to do is pick up the weapon blueprint from the Weapon Lab.

In order for you to access the Weapon Lab, you have to turn on the power. Follow this guide to learn how to turn the power on in Firebase Z.

Once the power is on, you can enter the room and take the weapon blueprint.

2. Dimitri Kuhlkay's Eyeball

This next step is not for the faint of heart. You have to make your way over to the Scorched Defense area of the map and find a dead body. Not just any dead body, but the body of Dimitri Kuhlkay, the inventor of the R.A.I. K-84.

Once you find his body, interact with it to pluck his eyeball from his skull with a knife. You will need his eye to perform a retina scan.

Take his severed eye back to the Weapon Lab and scan it at the computer that reads "Prove You Are Me." The scan will take a few seconds and then a drawer will open, take the keys that are in the drawer.

You can now interact with the computer, more details on that later in this article.

3. Barrel Assembly

With the key, you just got from the drawer, head over to the barracks area of the map located just past Tombstone Soda. Here, you will notice in the two green tents there are lockers. The key will open one of these lockers which causes a Mimic to spawn in.

Mimics are the brand new enemy type in Firebase Z that can transform into any droppable item and get the jump on you.

Once you have defeated this Mimic, it will drop the Barrel Assembly needed for the wonder weapon.

4. Radar/Dart Board Part

As mentioned earlier, you can now interact with the computer in the Weapon Lab. Interact with it and you will notice a radar spinning to different locations within the circle.

Wherever the radar lands in the circle, you must shoot the corresponding number on a dartboard all the way back in the Village Mess Hall.

Since the radar ping and the dartboard partitions are identical, you can match them up and figure out which numbers need to be shot.

These numbers change every game and you must do them in the order the radar on the computer shows.

Once you have figured out which numbers you have to shoot, shoot the numbers and then the bullseye in the middle. A secret compartment will open and give you another part for the wonder weapon.

5. Power Cell Part

The final part required to build the R.A.I. K-84 is the power cell.

You need to wait for a Mangler to spawn in on the map. Once one is on the map, you have to kill the Mangler by shooting its cannon arm off so that it drops the uncharged power cell.

Take the uncharged power cell to the Weapon Lab and place it on the charger. You have to wait for two rounds for it to fully charge.

Once fully charged, you can pick up the power cell and move on to the final step of this quest.

6. Build the R.A.I. K-84 Wonder Weapon

Now that you have collected all of the parts, you can go back to the workbench where we picked up the blueprint for the wonder weapon and assemble it.

The R.A.I. K-84 is an assault rifle ray gun that has two features, a full-auto, and grenade launcher firing mode. Press up on the d-pad to change the firing mode.
