Unlock the CRBR-S Wonder Weapon via Mauer Der Toten quest

There is the main Mauer Der Toten quest that will guarantee you a CRBR-S Wonder Weapon, but as with most special Zombies objectives, the process is very convoluted.

Here is what you’ll need to do:

  1. First thing you’ll need to do is build Klaus – check out our full guide on how to do that here
  2. Head to the ‘Switch Control Room’ and command Klaus to go near the locker in there, he’ll proceed to smash it up
  3. Take the light inside of it
  4. You now need to find numbers scattered around the map, and the first one can be found inside the ‘Garment Factory’
  5. Each main number will always be in the same location, but the additional numbers in eachg location will change, so make sure you’re making note of the new numbers each time.
  6. Main number two is in the ‘Service Passage’ – so see what numbers are in there
  7. Next up is the ‘Grocery Store’ – repeat the insructions above
  8. Now that you have 6 numbers, go back to the room you found Klaus in, and enter the numbers in the right order into the safe
  9. Open the safe, and claim your CRBR-S Wonder Weapon!

How to upgrade CRBR-S Wonder Weapon

Cold War CRBR-S Wonder Weapon

One of the unique traits of this item is its ability to upgrade into three other versions in addition to its base energy-based pistol form.

Players can upgrade this weapon into its three other variations and the only way to do this is by picking up special Mod Kits that will drop randomly from Zombies. These Mod Kits will attach to your weapon and transform it into a completely new form.

CRBR-S Base Form

Without any modifications, the Wonder Weapon acts as a standard, but powerful Pistol. The main advantage of its typical state is that it also comes with a companion orb that floats around and shoots Zombies too.

CRBR-S Blazer Mod Kit

Blazer upgrades your CRBR-S into a literal melting machine as the gun becomes a laser beam rifle that can continue to fire and clear out a string of Zombies.

CRBR-S Defuser Mod Kit

The Defuser Mod essentially turns the Wonder Weapon into an extremely powerful Shotgun and eats up 5 rounds per shot guaranteeing destruction.

CRBR-S Swarm Mod Kit

The final mod is the Swarm Mod, and picking this up will transform the Wonder Weapon into a mini-handheld Rocket Launcher with lock-on capabilities.
