Call of Duty: Black Ops 4

Once you have obtained the BLUNDERGAT

you need to complete the following stages to make it a Magmagat, I found this video (not my work) really helpful

please also note:


if you are playing in a group:
Only one of you needs to complete the quest steps to unlock the magmagat, then the remaining players (as long as they have got a blundergat from the box) can instantly turn the blundergat into a magmagat by simply putting the gun into the machine where the first dog head spawns :)

As soon as you grab the gun back out the machine you'll be rewarded the achievement


I just wanted to add to this quick to give everyone a heads up: Me and my friends ran it again last night and we believe there is a slight bug with this … we had it where the gun disappears if you leave the house while its charging, also the timer on it, where you have to bash the barrels is off to. we had to run it twice as they kept randomly going out - which is a right pain.. hopefully this is something they will fix. the achievement is still obtainable it just might take an extra gun run if the barrels don't light or you run out of time

This is pretty simple to do.

First get the Blundergat. This can be obtained in one of 2 ways.

1) From the weapon box.

2) Complete the quest for it. The quest is a very long way of going about this but it will guarantee the Blundergat without the randomness of the box. I'll add a walkthrough to this at the bottom of this guide.

Once you have a Blundergat, make your way over to the Wardens House and place the weapon inside the fireplace. This will make it float in place. Now get kills inside the house and you'll see blue things drop from the zombies. Run into them and pick them up. Keep doing this until all 3 skulls above the fireplace turn blue.

Now for the tricky part. You must pick the Blundergat back up and make a run for the New Industries area. While running there you will see blue fire barrels, run into these to keep the Blundergat hot or it wont work. When you get to New Industries, place the Blundergat into the forge. Wait a few seconds and it'll become a Magmagat and you can collect it.

Quest for Blundergat.

Items needed: Hell's Retriever and Spectral Shield

Hell's Retriever

Ate the following locations you will see a hellhound on the wall. Kill zombies in all 3 areas until the hellhound goes away.

-New Industries
-Cell Block 2nd Floor
-Outside the Warden's Office

When this is done fast travel from the Laundry Room and you are able to pick it up while riding the fast travel.

Spectral Shield

Part 1 is found in a random afterlife box that changes every match.

Part 2 is a door. This is found in 1 of 3 locations.
1) China Alley. next to a zombie spawn, by a small blocked off door under some stairs.
2) Citadel Tunnels. Next to a pile of skulls by an archway.
3) Citadel Tunnels. Up the stairs, next to the door.

Part 3 is the key. This drops when you kill the Warden, Brutus.

Build it at either the Docks or Cell Block 3rd Floor.


Now that you have both parts the rest is easy. You need to throw the Hell's Retriever at skulls that are found around the map, they appear when you aim at them with the Spectral Shield.

Here are the locations:

Eagle Plaza. On top of an electrical pole.
C-D Street. Inside a cell.
West Grounds. On some stairs. In front of a white door that is half way up the stairs.
Roof. Right hand side.
Docks. Out on a wooden pillar in water.

Once all 5 are hit, the Blundergat will be on the table in the Warden's Office.
