"1969 at a V.A. hospital ( location classified) there was a chemical spill that leaked in to the morgue which re-animated the corpses. the military regained control and sealed the re-animated corpses in steal drums. The chemical responsible is called 245 Trioxin.
245 Trioxin was developed by the Darrell Corporation for the military. It was meant to be used as a pesticide to combat Marijuana crops. It would kill off healthy plants and mutate seed germination, so as to remove the pleasant affects once the new plant strain matures. The military had high hopes for 245 Trioxin, it would not only kill off and mutate marijuana plants but also infect other Marijuana plant not exposed directly to 245 Trioxin threw pollination.
What the Darrell Corporation failed notice before it was to late was the affect 245 Trioxin had on animal matter, living or expired. if inhaled, absorbed through skin swallowed or injected the infected will turn into a zombie class T 245. Time till infected changes varies based on the dosage. if exposed to body fluid or bitten by the infected, the victim will also turn into a Zombie class T 245. a corpse bitten by infected will turn into a Zombie class T 245. symptoms of exposure include flue like symptoms, lowered body temperature, Head ache, paleness of skin, stiffening of joints. this is however signs that the victim is already dead, and those conditions are actually sings of Rigor Mortise setting in. One should note that though class T 245 zombies are mentally defective, they do in fact retain much of who they where. Speech and many memories are retained. A re-animated corps has a heighten sense of smell and in particular, they can smell living brains and have been quoted “ Your brain smells rich and spicy”. Class T 245 Zombies don’t eat flesh its brains they want. when a zombie is re-animated it feels pain and the consumption of brains( endorphins )alleviates that pain, also military researcher have discovered that the electrical discharge from neurons in the brain is sought after by the class T 245 Zombies as this stimulates neuro receptors and facilitates ambulatory activity. they can feel old injuries that may have caused their death. they can also feel themselves rotting. The zombie becomes passive once it has eaten brain matter, this is only short lived and they will soon be in search of more brains. warning a head shot to the brain wont stop them. you could chop them up and the pieces will come after you. If you cremate them the ash could contaminate corpses in grave yards or even animal road kill. the infection is not limited humans. Just a quick note the class T 5 (Trioxin 5 ) Zombie are identical to class T 245 Zombies except a bullet to the brain will re-kill a T 5 Zombie. When the military realized the weapons possibilities of class T 245 Zombies, research was taken over by Pentagon Special Operations Department. Their researched showed a 25sec re-animation rate of corpses exposed to Trioxin 245 in its gas form.The most cost effective and safest means of disposal of infected is cremation. but an industrial bio filter is required to prevent contamination. the military had experimented with a nitrogen based endothermic bullet to suppress the infected, pressurized air was used as the propellant as a powder based propellant would damage the bullet and render the nitrogen ineffective. this attempted was a failure do to duration of inactivity of the infected subdued by the nitrogen based bullet which only lasted 1min 30 sec. In 1969 prior to the invent of bio filters. the re animated where contained in insulated steal drums along with nitrogen. Do to a military mix up some of these containers where shipped to the wrong locations. To this day not all of the containers have been accounted for. If a container is discovered, do not temper with it. immediately call the following number “311-555-8674“ where the military will provide further instructions." - Author Unknown
