'Seal the Deal' Main Quest Guide for Die Maschine in Black Ops Cold War Zombies

Call of Duty: Black Ops Cold War Zombies casts players into Die Maschine, an abandoned Nazi facility set in Morasko, Poland, with the ever-growing threat of an undead horde. At its core, player's are tasked with one goal - survive; however, the most experienced of Requiem agents are also tasked with closing the interdimensional rift found at the heart of the facility.

Seal the Deal serves as the Main Easter Egg of Die Maschine. The rewards for completing it are as follows...

Evil Unleashed Dark Ops Challenge (XP & Calling Card)
Silver Trophy or 30G Achievement (dependent upon the player's platform)

Congratulations to NoahJ456, CodeNamePizza, Starrburrst, and GeekyPastimes - the first team to complete the Main Quest! The hunt began on Friday, November 13th at 8:30AM PT and was completed on the same day at ~10:45AM PT, a total completion time of roughly two hours and fifteen minutes.

Seal the Deal

Prerequisites

Each of the following requirements must be met prior to various stages of the Main Quest in order to progress. Keep this in mind and fulfill these requirements alongside the Main Quest.

Turn on the Power.
Reforge the Machine.
Obtain the Nova-5, Cryo-Emitter, Electrobolt, and Thermophasic upgrades of the D.I.E. Shockwave.

Create the Aetherscope

To proceed with the Main Quest, you must have turned on the power and reforged the machine.

To collect each of the three Aetherscope parts, you must be within the Dark Aether.

The order in which the Aetherscope parts spawn is randomized, however, each part pertains to a single location.

Decoder: Particle Accelerator, near the Aether Tunnel
Antenna: Yard, beneath the concrete staircase
Radio: Crash Site, near the cockpit on top of the plane debris

The Aetherscope can be created at the workbench in Particle Accelerator.

Reveal the Spectral Reflections

To reveal the Spectral Reflections, you must be within the Dark Aether.

Navigate to the Medical Bay and collect Doctor Vogel's Diary, found on the desk beside the computer.

An anomaly will spawn in the lower portion of the Medical Bay, interact with it to reveal the Spectral Reflection. Interact with the Spectral Reflection once again to give it Doctor Vogel's Diary and begin a narrative sequence. Subsequently, a Mayak will spawn nearby and must be killed to proceed.

Repeat this process for two more Anomalies, found in the Control Room and Particle Accelerator.

Lastly, return to the computer in the Medical Bay and interact to enter the password.

Obtain the Dark Aether Wrench

To proceed with the Main Quest you must have obtained all four D.I.E. Shockwave upgrades.

Navigate to the Medical Bay and locate the large machine on the ceiling. Each of the four extremities of this machine correspond to a D.I.E. Shockwave upgrade, shoot each extremity with its designated weapon to raise it.

D.I.E. Nova-5: Nearest to staircase to Control Room
D.I.E. Cryo-Emitter: Nearest to Weapon Crate
D.I.E. Electrobolt: Nearest to Mystery Box
D.I.E. Thermophasic: Nearest to Speed Cola

Enter the Dark Aether via the Anomaly found in the Medical Bay near Particle Accelerator.

An Anomaly can be found on the upper catwalk of the Medical Bay, interact with it to reveal the Spectral Reflection. Once the narrative sequence completes, the Dark Aether Wrench can be collected from the ground near the Spectral Reflection.

Install the Decontamination Agent

Navigate to the Yard and locate the Tank. Interact with the Tank three times to use the Dark Aether Wrench, revealing a Zombie in the Tank's hatch. Then, kill the Zombie. Once the Zombie within the Tank is killed, throw an explosive equipment, such as a Semtex, at the Tank hatch. This will cause the Tank to fire at a tree in the Crash Site.

Navigate to the Crash Site and collect the Decontamination Agent found on the ground. With the Decontamination Agent in hand, return to the Medical Bay and interact with the Containment Unit to install the Decontamination Unit.

Start the Purification Process

With the Decontamination Agent installed, proceed through the rounds until a Megaton spawns, then deal damage to it until it splits into the Megaton Blaster and Bomber enemies.

One at a time, lead the Blaster and Bomber beneath the large machine on the ceiling of the Medical Bay. If done correctly, the enemy will be lifted into the machine. Once each of the two Megaton enemies are within the machine, interact with the computer found in the upper portion of the Medical Bay to start the purification process, this will begin a narrative sequence.

Obtain the Orlov Family Photo

To obtain the Orlov Family Photo, you must be within the Dark Aether.

Locate the Anomaly within the Omega Outpost, interact with it to reveal the Spectral Reflection. Once the narrative sequence completes, collect the Orlov Family Photo on the nearby desk.

Particle Accelerator Deactivation

Once the Orlov Family Photo has been obtained, all players will be teleported to the Particle Accelerator where a narrative sequence will begin.

Orlov will then begin to deactivate the Particle Accelerator. This process is split into three stages, the Magnetic Containment, Primary Coolant, and Fail-Safe. Players must protect Orlov while he deactivates the Particle Accelerator.

Once the Particle Accelerator is deactivated, lethal beams of electricity will spawn throughout the map. Players are given 90 seconds to reach the Exfil Site and board the Helicopter at the Pond.
