CALL OF DUTY ZOMBIE WALKTHROUGH UPGRADE

Interact with it, and the upgrade is complete.

Near the door between Medical Bay and Particle Accelerator you'll find a box with chains.

CALL OF DUTY ZOMBIE WALKTHROUGH FULL

Interact with the Mutated Fungus to 'collect Cryogenic Liquid.' Wait at least 30 seconds, and you'll come back to the flask to find it's full and listed as a Filled Flask.Get the Megaton to fire sludge at the tree. Wait for a Megaton to spawn, and lure it to the purple Mutated Fungus bulge that appears on a tree near you in Crash Site.Hop down to the Pond area where the box falls, and an Empty Flask will be in its place.In the 'Penthouse' area, there's a box on the edge of the Pond.Do it three times and the Electrobolt is yours.

After shooting it, go for the next crystal and come back.

After collecting each individual crystal, go to the bottom floor of Particle Accelerator and look for a box in the southwest corner.

The third is near the cave in Crash Site. A second is right of the Mystery Box in the Pond.

There's one on the roof in 'Bedroom' near Stamin' Up.

For this task you need to suck energy from three crystals using the left trigger attack of the D.I.E.

Start by going to the Particle Accelerator room and enter the portal under Pack-a-Punch.

Back in the real world, go to the Pond and you'll see the upgrade on the back of a truck.

Quickly go to the Weapons Lab before your Aether expires and interact with the Plasma Cutter across from the perk machine with the big skull on it.

It will add a cartridge to your inventory.

At the Crash Site, melee the box below the hovering aircraft.

If you've done everything right up to this point, you should see a portal in the Pond area.

Once you've done it, go back to the hole to unleash the weapon. Get up to 30 zombie kills to fill it with souls.

Go to 'Living Room' and head to the hole in the wall that has 'PL' in graffiti written below it.

Take the card to the big machine in the Weapons Lab near the Mystery Box.

Pick up the Keycard dropped by one of them.

Kill one of the green Megaton zombies and the pair of foes it splits into.

Shockwave is a highly versatile Wonder Weapon. Shockwave Wonder Weapon with all its upgrades.

In the regular world, go back to the Medical Bay computer and interact with it to enter the password.ДЇor the next part of the Easter egg, you need at least one D.I.E.

CALL OF DUTY ZOMBIE WALKTHROUGH TRIAL

One is near some shelves in the Medical Bay, one is in the trial area of the Control Room and a third is near the bench you used to craft the Aetherscope. Interact with them to make them appear and give them the diary.

Three Spectral Anomalies (or ghosts) will spawn as orbs.

You'll see Doctor Vogal's Diary sitting there.

Go to the next portal that spawns on your map and look for an old computer in Medical Bay.

From there you can leave the dark world and build the Aetherscope at the bench near Pack-a-Punch. One part can be found by the stairs in the Yard (spawn), another is atop the plane in the Crash Site and a third is in the Particle Accelerator room near the fast travel point.

Your next step is to find three Aetherscope parts that can spawn in any order.

Once Pack-a-Punch has been enabled, a new portal will spawn that's marked on the mini-map by a diamond-shaped icon with a star inside.

If you like what they do, it doesn't hurt to subscribe. To augment our work, check out the video below from MrDalekJD as well. With those basics out of the way, it's time to get to the proper Easter egg steps. Place the part in it, and you'll be teleported back with the machine in use.

Go back to the portal location, and you'll see the outline of the Pack-a-Punch machine.

You'll fall down into a room with a Machine Part you can pick up. It's marked by a big, purple circle on the ground.

In the dark world, follow the waypoint to the Aether tunnel.

Interact with both of them, and a portal will spawn in the middle of the room.

There's a kiosk on the left and right sides of the big Particle Accelerator room.

To get to the power, follow the path from Yard > Omega Outpost > 'Bedroom' > Crash Site > Tunnel > Control Room > Medical Bay > Particle Accelerator and hit the big red button to turn on the Main Power.

Just like all recent Zombies Easter egg quests, this one mandates turning on the power and Pack-a-Punch machines first.
