At approximately 1230 hours on Tuesday, October 14th, sensors at the National Irresponsible Research Laboratory in Chicago reported an Expected Apocalypse Event involving a lethal biological agent. The incident has been traced to a lone researcher who accidentally shattered a vial of zombie virus while eating his lunch. Per standard procedure, the laboratory was instantly sealed from all outside contact, and the laboratory automated sensor system immediately began analyzing the environment for any pathogens.
Upon verification of exposure by automated and manual systems, the CDC triggered Phase One of its SHAD Protocol. As a Phase One risk factor, the exposed researcher was immediately Shot in the Head And Decapitated by the cleanroom’s Containment Drone. The contents of the room were subsequently incinerated at a temperature of 2000°F, followed by radiation exposure sufficient to make the surrounding area lethal to all forms of life for the next 500 years.
