With each new map that reaches the Call of Duty Zombies, fans expect a new and exciting miracle weapon. Something that is powerful and that makes it stand apart from all the other special weapons that have made their presence visible over the years. In Mauer Der Toten it takes the form of CRBR-S (pronounced Cerberus). This way you can get a free CRBR-S in Mauer Der Toten in Call of Duty: Black Ops Cold War.
To get the free CRBR-S, you must first turn on the power, activate the Pack-a-Punch machine, and restart the Claus robot. When all is done, take Claus and go to the Control Control Room (the room to the right of the Mule Kick). Use Claus’s remote control to tell him to go right in front of the box with the zero painted over it. It stabs and you can catch the black light inside.
Now that you have a black light, your normal flashlight will change. With this you have to go to three specific rooms and find three sets of numbers. These are two-digit numbers that will be used to open the safe, so if you don’t remember them, write them down.
Quick note: all three numbers will be random for each match you get into. They will also not always be in the exact same place, but will be in the rooms specified below. Look high and low at the walls to find them. Make sure you use black light; otherwise you will not see the numbers.
The first number you need is at a clothing factory. In our game, the number 23 was on the board.
The second number is in Service Passage. Our number was 05, directly opposite the ladder.
Finally, the last code is in the Grocery Store and ours was 09 on the wall shelves.
Remember that your codes will be different from ours and elsewhere in this room. After memorizing all three numbers, go to Hotel Room 304 and the same room where you grabbed your hands to activate Claus. To the right when you enter is a safe. Enter three numbers in the correct dial and the safe will open.
If you can’t figure out which dial you’re on, start from scratch and count the clicks you make until you get to the right place. Be careful when playing solo. While entering the codes, the zombies are still attacking you, so be quick. When the third correct code is entered, the safe will open itself and you can grab the CRBR-S.
