A month earlier a large armed group entered and stopped production at this facility. What was found was a morbid scene of using human dead and processing them into a genetic goo, that is then used to nourish/enhance the cloned zeds.
Shortly an investigative team will arrive to find out what they can about where the bodies were comming from and where the "product" was being taken to. The container ship in port is full of dead bodies, the processed goo was then taken out by rail and truck.
Your mission is to enter the facility and clean out any remaining zeds so the investigative team can do thier work in safety and find a way to shut down the facility permenantly.
