Mauer der Toten Guide | Black Ops Cold War Zombies

CBRS-S

The CBRS-S is a pistol that fires two high-energy shots per ammo used, thanks to the Copy-Cat Orb floating around the gun. It can be Pack-a-Punched and has three variants. Available from the mystery box, trials, or via the following quest:

1. Assemble the base version of Klaus.
2. Have Klaus open the Locker located in the 'Switch Control Room' by using the Tactical Equipment to move him in front of it.
3. Pick up the Blacklight from the Locker.
4. In the following three locations, a number on a wall is only visible with the blacklight (coloured blue):

   Location / Dial	Spawn Points
   Garment Factory (First Dial)	Chalkboard Doorway Graffiti
   Service Passage (Second Dial)	Doorway Pipes Electrical Box
   Grocery Store (Third Dial)	Mugs Poster Shelves Watermelon Poster

5. Once you have all three numbers, go to 'Hotel Room 305' and use them to unlock the Safe.
6. Once you enter the right combination, the safe will open revealing the CBRS-S ready for pickup.

Swarm, Blazer or Diffuser

• All variants drop from killing Zombies. There is no way to force a specific variant to drop.
• Once a variant runs out of ammo, the CBRS-S will return to its base variant.
