CoD: Black Ops Cold War Zombies - All Easter Eggs

In our Easter Eggs Guide to Call of Duty: Black Ops Cold War you will learn:

  • Where and how to activate all Easter Eggs
  • What happens when you have found them all

Christmas is just around the corner - so it's the perfect time to search for virtual 'Easter eggs' or Easter Eggs in Zombie Mode!

Easter Egg Part 1: Pack-a-Punch

The first thing you need to do is unlock the Pack-a-Punch machine. To do this, you need to go to the lab in the bunker (the way there is automatically marked by the game). In the bunker, activate the power and the portal. Enter the aether dimension through the portal and look for the Pack-a-Punch machine there (also marked).

This portal leads into the ether.

The Pack-a-Punch machine - once unlocked - is located under the particle accelerator in the bunker.

Easter Eggs Part 2: Find the T.O.T. Machine

Now you have to wait until a radioactive mini-boss appears. Shoot him until he splits in two and then finish him off. When he dies, he drops a golden key card. Pick it up and go to the weapons lab in the bunker.

Put the key in the weapons cabinet and you will get the T.O.T. remote control in return. Run back upstairs to the main building (the colorful concrete building). Stand there in front of the hole that lets you see into the room with the machine. Activate the machine so that it sucks in all the zombies that walk by.

Here you will get the T.O.T. remote control.

Lure as many zombies as you can to the beam. Once the machine has eaten enough zombies, you can interact with it again at the hole. You will have to repeat this process several times, as the machine will have to cool down after some time. Press the interaction button to unload the machine.

Now enter the room through the now open door. The T.O.T. Shockwave machine is waiting for you there.

Easter Eggs Part 3: T.O.T. Machine Cryo-Emitter Upgrade

Go to the roof of the main building. Shoot the wooden box on the roof. After the box falls down, run to it and pick up an empty bottle there. Nearby, an ether mushroom grows on a tree - go there as soon as boss zombies appear again.

Don't kill the boss zombie right away, but instead stand next to the mushroom and then let the boss shoot at you - it has to hit the mushroom. The hit mushroom will release a purple liquid, which you will pick up in the empty bottle. This can take some time, so meanwhile kill the boss. Also this time he drops a golden key card.

The T.O.T. machine sweeps everything away.

Now run back down to the infirmary in the bunker. There is a blue box locked with chains. Melt the chains with the bottle. Voilà, the Cryo-Emitter update is now installed in the T.O.T. machine!

Easter Eggs Part 4: T.O.T. Nova-5 Upgrade

On the second floor / roof of the main building, there is a golden canister on a platform. Suck the canister towards you using the T.O.T. Shockwave machine. Run back to the weapons lab and put the canister into the white machine.

The machine sucks in the zombies just like that.

Shoot the spawning plague dog and then collect the canister again. Now run to the crash site (area with the crashed plane). There is a crate overgrown with roots on which you can place the canister. Shoot the canister to get the Nova-5 upgrade!

Easter Eggs Part 5: The Etherscope

First you need the three etherscope parts. The parts spawn one by one in the Aether Dimension. The first part spawns on the crashed plane, the second in the lab with the pack-a-punch machine, and the third in the junk under the stairs in the starting area.

Once you have all three, you'll craft the etherscope at a workbench.

Easter Eggs Part 6: Finding Dr. Bird's Ghosts

Enter the ether dimension again, then collect Dr. Vogel's diary from the old desk in the infirmary. Now three ghosts spawn on the map (Only in the Ether Dimension!).

The first ghost spawns in the infirmary, but in the office on the floor below you. Let the ghost talk and then give him his diary. Repeat this in the control room in the bunker. You will find the last ghost in the particle accelerator room.

Pay attention to the monologues of the ghosts! They will tell you one letter each for the password of Dr. Vogel's computer in the infirmary. Enter the password on the PC in the normal world.

Easter Eggs Part 7: T.O.T. Electro-Bolt Upgrade

Next, an ether portal spawns nearby, which you enter. Now you need to charge three T.O.T. Shockwave shots with crystals and shoot them into the portal one at a time.

Crystal #1 is at the crash site, the second is on the roof of the main building, and the third is by the pond behind the main building. Shoot them all into the portal to get the Electro-Bolt upgrade.

Easter Eggs Part 8: T.O.T. Thermophasic Upgrade

You can get the last upgrade by collecting fuses in the ether. Step through the ether portal on the frozen pond and run to the crash site. The fuse is under the floating plane wreckage.

Now head (but quickly!) to the weapons lab where you install the fuse into the plasma cutter. Then return to the pond in the normal world. The last weapon upgrade is in a crate on the truck.

Easter Eggs Part 9: Decontamination

In the infirmary, you will now shoot the floating cylinders with the T.O.T. machine. Each cylinder must be shot by a different upgrade variant. After that talk to the ghost on the top floor of the infirmary (ether dimension!).

The ghost will show you soldiers who stole the Aether Wrench. Look at where they dropped it. Collect it in the normal world. After that, run to the tank by the pond.

Important places and items are sometimes marked.

Repair the broken parts of the tank and kill the zombies that come out of the hatch. After that, craft a Semtex and throw it into the hatch. The tank will now shoot a tree, summoning the decontaminant.

Put the decontaminant into the glass container on the wall in the infirmary. Wait until a radioactive boss spawns. Shoot it until it splits in two and then lure it under the cylinder. Activate the cylinder at the computer terminal.

After that, go to the main building in the ether dimension and talk to the ghost there.

Easter Eggs Part 10: The Final Battle

Pick up the photo of Orlov and you will be teleported to the particle accelerator room. Defend Orlov from zombie attacks for three waves Once he's done, escape from the map via exfiltration.

Hurry though, as you only have 90 seconds. With the escape you have mastered the Easter Eggs hunt. The reward is a secret sequence!
