19th.October.1998: The first Zombie was discovered. It‘s a different species we don’t understand. We call him “Zombie” because it looks like a stereotype “Zombie”. It was very calm when we found it, and it didn’t do anything, when we took it to the “underground-labor” by “Texcorp”. They found a Brain-Illnes, when they examined the deformed skull. Everyone knows what that means: the immortal human, if they only could get him, a comfortable IQ! 
15th. November. 1998:
But, there was a problem, when they trained him. It seems, that it….HE was already much more intelligent than we thought. He killed two people and ran away. Right, at the same day, the news reported the death of two civilians. Witnesses talked about a sick looking “man”, who ran to the civilians and ate them. 
Chapter 2
You’ve got the task to fight the “Zombie-Nuisance” and just found an old file, from the locally prison
Name: Collin Danbrook
Birth: 1975
Imprisoned: 1988, 1989, 1991, 1995, 1997
Escaped: 1995, 1997
The 23-year old COLLIN DANBROOK got cancer in 1997. When they tried to protect him from his brain tumour, he got paranoid. He said something like “deadly experiments” and “test object”. He injured one doctor (probably deadly) and the other one said, that he said: “I won’t spend the little rest of my life in jail!!”. Then he ran away.

Surveillance recordings, Prison*
13th. June. 1997.
A man runs across the terrain of the prison. He gets slower, struggles and falls down. After a few seconds, he. tries to pull himself further, with his arm. Then, he just lays there. 24 minutes later, the cops appear on the cameras. They’re tired and don’t find him. So, they return to the prison. 
Chapter 4
News
The “Zombie” continues multiplying. Ever human it bites, gets a “Zombie”. They’re primitive, but dangerous. Also, the “first Zombie” is getting bigger and stronger.
Witnesses claim, that it’s already able to throw their car. Scientist call it the “Tyrant”. 
Chapter 5
In a laboratory, wich explores the case of the “Zombie-Apocalypse”
A victim of the “Zombie-Reproduction” was found dead and got examined. Her stomach got cut open and a strange organism was found. It attacked  the body like a parasite. With each bite, from the first “Zombie”, a little bit of…. him, mixed with some Bacteria from his    mouth, got into the body of the victim. But the DNA was not from any human being…..
Chapter 6
Back at the Surveillance recordings
Actually, an animal, not able to identify, it’s dark, walks to the half-dead body. After a while of critical watching, it sits down and starts to brood.
A few months later, the animal runs away, because the half-dead body moves. 
It shouldn’t be too difficult to create an “animal-venom”! And after the “Zombie” somehow came in contact with it (gas or liquid), we can kill every single “Zombie” and he can’t reproduce. Then, it’s all over….I mean.. that’s the plan….
