|Profession:||Black Ops soldier|
|Cause of death:|
Zimmer was a Black Ops soldier who was part of a black operation to weaponise the Rage Virus.
Zimmer's objective was, along with that of the rest of Al's men, to capture Infected for Dr. Billingsworth in the latter's attempts to weaponise the Rage Virus. Thus, Zimmer initiated a plan to force the Infected out by setting Infected-filled forests in Scotland on fire. This plan worked, and Zimmer, Al and several other soldiers captured numerous Infected, along with survivors Selena, Douglas, Derrick and Clint Harris, and brought them back to their camp.
However, the forest fires Zimmer caused eventually went out of control due to a lack of rainfall to put them out, and they eventually reached the personnel's camp and wiped it out. It is unknown what happened to Zimmer, but he was most likely killed when the forest fire reached the camp, either by the fire, or by the captive Infected that Selena released.
