CBRS-S

The CBRS-S is a pistol that fires two high-energy shots per one ammo used due to the Copy-Cat Orb floating around the gun. It can be Pack-a-Punched and there are three variants.

The CBRS-S is available from the mystery box, through the completion of trials, and 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, there will be a number on a wall only visible with the blacklight (coloured blue):
1. Garment Factory (First Dial):
• Chalkboard
• Doorway
• Graffiti
2. Service Passage (Second Dial):
• Doorway
• Pipes
• Electrical Box
3. Grocery Store (Third Dial):
• Mugs Poster
• Shelves
• Watermelon Poster
5. Once you find the three blue 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 the variants can be obtained by killing Zombies. There is no way to get a specific variant to drop other than just waiting for one to drop.
• Once a variant runs out of ammo, the CBRS-S will return to its base variant.
