Have you got your hands on Mauer Der Toten's Wonder Weapon yet? If you have, here is how to upgrade CRBR S by collecting mods.

As promised earlier, Call of Duty Black Ops Cold War Season Four Reloaded arrived just a few hours earlier, bringing the anticipated Mauer Der Toten map for Zombies' Easter Egg hunters.

Wonder Weapon on its own could be an easter egg as well, but the one that helps you finish other easter eggs easily. While the base version of CRBR-S is already a powerful weapon, you might want to upgrade it to deadlier variants.

How to Upgrade CRBR S in Mauer Der Toten

Overall, CRBR-S features three variants in the Mauer Der Toten map. In order to get each one of the variants, you will only need to pick up its dedicated mod kit.

Unfortunately, there is no certain location to collect the mod kits. They are random drops that you can earn by killing zombies. So, just get the base version of CRBR-S and start killing zombies to get them to drop you a mod kit. Once you pick up the mod, the CRBR-S in your hands will turn into a new variant.

All CRBR S Mods

  • Base Version: A pistol that shoots two bullets simultaneously.
  • Blazer: An Assault Rifle shooting laser bullets.
  • Diffuser: A shotgun with a wide range.
  • Swarm: A rocket launcher with the ability to lock on enemies.

Keep in mind that once you run out of ammo for a modded version of CRBR-S, you will lose the mod and the Wonder Weapon will turn into the base version again. (Thanks, Ulterior Covert!)
