The DIE Machine is Zombies' most powerful weapon
First of all, there are prerequisites for obtaining this powerful weapon. You will need to know how to turn on the power and it will come in handy if you also pack your guns to make yourself stronger. In this guide, we are going to show how to do all of this in the video below. The other requirement is that you travel far enough in zombie mode to meet the zombie Megaton, as it will contain a key element to successfully complete this challenge. So below is a video that goes from the start of zombie mode to the point where we get the DIE Machine. In the text below we will start the instructions from the moment we get to the Megaton Zombie.
Switch on the device
Get Pack-a-Punch
Kill Megaton Zombie
Assuming you've made it this far to level 10-11, you'll encounter the Megaton Zombie first. This zombie will be easily identifiable because it is a bright yellow color. He is also much stronger than normal zombies. Once you kill its first form, it will split into two smaller zombies. Once you've taken down the Megaton and its spawn, you'll find a keycard item that's been left behind.
Take the Keycard and go to the weapons lab
The arrow in the image above points to the weapons locker. Until you have the access card, you cannot interact with this machine, but once you have it, it will give you the item you need to get the DIE Machine. Insert the key card into the weapons locker and a drawer will open. Take the DIE Remote Control.
Take the DIE Remote to the living room
The DIE The remote controls the DIE weapon, which is actually hidden in the living room area. The hole in the wall in the image above is where you want to go. Go into the hole with the remote and you can turn on the device. This will start the operation of the weapon and suck up any zombies that cross its path.
Try to get as many zombies into the DIE Machine as fast as possible
Once you turn on the machine, it will suck up zombies as it passes. You'll want to try and time this for a time when you have the most zombies nearby, as you actually have to feed the machine a few zombies. If you don't get enough time, the machine will stop and need to cool down. If this happens, try to waste time and preserve the zombies in the area. Wait a few moments and then turn the machine back on to continue the process. Once completed, you will need to unload the DIE machine.
Unload the machine and it will blow up the door. Inside is the weapon
Go back to the hole in the wall and interact with the machine again to unload the weapon. At this point the door will open, look inside to grab the DIE machine and complete this Easter Egg for Black Ops Cold War Zombies.
