The Sniffers are enemies which appear in some maps. Every round they increase in speed, number, and health.
Not much is known about their creation, but relating to old Nazi documents it says that they were created by Dr. Hans Eicke.
These Zombies are a bit harder to kill with under-powered weapons such as the M1911, M14 and Olympia. They can die from one shot by a Ray Gun. After round 25 they will become much stronger. They attack with their hands, or sometimes they will have a dynamite strapped to their body.
These 'Zombies' are based from the Sniffers from Wolfenstein (2009).
