How to use

In the Call of Duty: Black Ops 6 Zombies map, Shattered Veil, completing the main Easter egg quest requires access to the Ray Gun Mark II.

To do this, at Round 10 enter the Mainframe Chamber room (Pack-a-Punch room) and wait for the special Lab Technician zombie to spawn.

Killing the Lab Technician will drop a Floppy Disk. Take this to the East Foyer (Stamin-Up area) and insert it by interacting with a computer unit on the table by the staircase.

You will need to wait a short period in this room while the fax machine next to the computer prints a message. While it prints, waves of Vermin will spawn.

Once printing has finished, interact with the fax machine. You will see a dialog box on your screen displaying the contents of the fax.

The majority of the fax is useless information. What you need to look for is the animal name in capital letters. This will either be YETI, MOTH, WORM, or CRAB.

With this information, enter the Nursery room (PHD Flopper area) and locate the child's chalkboard.

This chalkboard has four known variations. You can identify which one is in your game by reading the group of letters in the top left.

Either: Input your word and chalkboard variant into my solver to get the door code OR...

Using your word e.g. WORM, look for the first letter on the chalkboard (W in this example).

You will notice that letters are grouped together on the chalkboard. Count how many letters are a part of the group that makes up your first letter (e.g., 9).

This number is the first digit in your four-digit code. Repeat this process for all additional letters to get the full code.

With this code, head to the Service Tunnel. You will find a trapped Doppelghast behind a glass door.

Enter your code into the keypad on the door. This will release the Doppelghast.

Killing the Doppelghast will drop a Severed Arm item. Pick it up and take it to the Armory room.

Interact with the display case security scanner in the Armory and use the Severed Arm on it to open the case and obtain the Ray Gun Mark II.
