But which Mauer Der Toten Wonder Weapon is best and what do they all do? We’ve got all the information you need, right here.
Base CRBR-S

First of all, the base CRBR-S Wonder Weapon looks and acts like a standard laser pistol. It doesn’t seem to different from the R.A.I. K-84 that players may remember from Firebase Z, except that it has a rotating bullet orbiting it that will also fire on enemies.

Picking up an upgrade with this base Wonder Weapon will leave you with a more impressive gun, however.
CRBR-S Swarm

The CRBR-S Swarm fires a swarm of lock-on missiles at your target when fired. The weapon mod uses 4 ammo per shot but deals significant damage to the undead.
Despite being a lock-on weapon, the Swarm can still be rapid-fired to deal some real damage and explode any enemies in your path.
CRBR-S Blazer

Obtaining the Blazer upgrade will turn your CRBR-S into a proper rifle, and this one is a powerhouse. Firing a laser, the weapon is excellent at dealing big damage to single targets, or quickly dispatching a crowd.
However, the Blazer does little area of effect damage, unlike some of the other mod kits.

CRBR-S Diffuser

On the other hand, the CRBR-S Diffuser is the perfect crowd-control weapon, firing shotgun blasts into incoming hordes. Get up close and personal to hit bosses with multiple Diffuser shots, or keep your distance and thin the crowds with ease.
The CRBR-S is designed to be switched continuously, so don’t be afraid to switch up your Wonder Weapon with new mod kits when you find them.
