Safe Code - Mauer Der Toten Cold War

The Mauer Der Toten is a new introduction to Cold War Zombies and one of the most interesting things about it is the new Wonder Weapon you can acquire by retrieving a safe code. However, the code is randomized every time, so it isn’t as simple as finding the correct sequence once and using it over and over again. In this Safe Code – Mauer Der Toten Cold War guide, we will tell you the fastest way you can get your hands on the CRBR-S Wonder Weapon locked inside a safe in Hotel Room 305.

Mauer Der Toten Safe Code

To start with, the first thing you will need to do is to build Klaus. If you do not know how to do this procedure, we have an in-depth Klaus-building guide. After you have built Klaus, you will need to get him to the Switch Control Room. Once there, instruct him to break open the locker that has the number 0 on it. Inside you will find a blacklight. Pick it up. You will notice that the light on your weapon has changed. With this, you will now be able to see hidden numbers scattered around the map.

While the safe code numbers are different each time, luckily the locations where they are found remain the same. You will be able to spot these areas thanks to a number in a black circle. These just represent which number in the safe code sequence, you need the blacklight to see the actual number. The first number can be found in the Garment Factory, next to a staircase. The second number is in the Service Passage tunnel, left from the ladders that lead below the street. The final third number is in the Grocery Store, in the corner of the room. All that’s left now is to return to Hotel Room 305 (the same one where the Klaus Hands are located) to get your prize.

    The 2ed number for the safe code doesn’t appear for me, is it some kind of bug/glitch or what?

      That’s because all the numbers spawn in several different places I only know that for the second number they can spawn just above the door way

    Does anyone know if only 1 player can get the CRBRS out of the safe with code. Or can all 4 use code for safe.
