Dark Aether Wrench
There will be a new portal that will spawn right after you’re done lifting all the container legs. This anomaly is located at the exit towards the particle accelerator, or the Pack-A-Punch room from the Medical Bay.
Go through this anomaly and go back up to the Medical Bay. When you are in the Medical Bay, you will see another blue orb outside the computer office.
Interact with it, and two spectral reflections will be spawned. Let them finish talking and you will be spawned back into the real world. You will notice a Dark Aether Wrench on the floor.
Pick it up and go back to the spawn point near Nacht. You can now hit the tank at the spawn point three times with the wrench.
After hitting it three times, a zombie will come out of the entrance hatch at the top.
Kill the zombie and then throw any kind of explosive (Semtex, C4, etc.) at the hatch. The tank will fire a shot upon explosion.
Decontamination Agent
Go back to the plane crash site and you will see a golden “ball” on the ground. This is a Decontamination Agent.
Be careful. As soon as you reach the agent several plaguehounds will spawn around you. Take them all out, pick up the agent, and bring it back to the Medical Bay.
You will see a containment unit on the wall where the last spectral vision was seen. Insert the Decontamination Agent in the Contamination Unit and you’re done with this step.
Megaton Conversion Step
Now you must wait until a Megaton spawns in. When it does, kill the Megaton and wait for it to split into the Megaton Blasters.
Once you get the blasters, lure them under the big hanging container in the Medical Bay, and they will be sucked into it. Both blasters must be sucked into the container.
After they’ve been sucked into the container, interact with the computer in the office, and the splitters will now be merged back into a Megaton named Orlov, who can talk.
Boss Fight
You must wait for Orlov Megaton to finishing talking and he will escape the container by running towards the particle accelerator room.
The particle accelerator room will now be super dar, and you need to lure Orlov out somehow.
But before going any further, make sure you have stocked up on all the perks, weapons and any other equipment you might need to survive a boss battle. We recommend having the following setup by now:
- Gallo SA 12 Shotgun – Tier 2 or 3 Pack-A-Punched
- D.I.E Electrobolt (Electric Upgrade)
- Level 3 Armor Unlocked
- 5 Stim Shots
- C4 or Semtex
- Perks: Jugger-Nog, Stamin-Up, Speed Cola & Deadshot Daquiri
The above setup might look really expensive, but by the time you reach the boss fight, points won’t be hard to come by. It was easy for us. And remember, the fight will be in the particle accelerator room, so you can always repair your armor as long as you have enough salvage. You won’t run out of salvage as there will be many zombies in the boss fight.
Let’s continue. Go to the living room of the Nacht and you will see another portal there.
Go through the portal and go to Nacht’s ground level, near the Omega outpost by the Pistol wall buy. There will be another blue orb.
Interact with it, and another spectral vision will be played where you will see Orlov in his human form.
Once he is done talking you will be teleported back to the real world. You will notice that there is a family photo of Orlov on the table.
Pick it up and you will be teleported, for the final time, to the Pack-A-Punch platform where Megaton Orlov will look at the photo and remember his family.
The Boss Fight is not against the Megaton Orlov but with him! Orlov will talk about destroying the particle accelerator, and he proceed will to do so. While he is doing that, you need to protect him from incoming waves of zombies. The zombies will include normal zombies and mini-bosses. This is why you need to be prepared before jumping into this boss fight. Orlov will move to three different locations around the particle accelerator where you must protect him from the zombies.
