In the year 2066, the world seem to be at a rather calm time. There were little to now battles and there hadn't been a full on war in 30 years. But little did people know, that was all just a front.

In a secret lab, some scientists in Asia were looking for the perfect way to deal as much damage to the U.S. as possible. After years of testing, they had finally found their answer. They made a virus that was completely undetectable. It had no sign, and spread very easy through transmission of body fluids. And the worst part was, it could remain dormant for years, until a person's stress levels would trigger the virus to mutate and take over turn the person into a zombie.

They sent 4 very beautiful woman to Austin Texas. With in a week, the women had been with 10 other people each, and those people had then been with 2. With in a week, thousands in Austin had been unknowingly infected.

Then it happened...

College fall midterms, football and volleyball playoffs, work layoffs...

They all lined up at just the right time, and then boom!

A guy in a boardroom, a cheerleader at lunch, a football player in the locker room, a college athlete failed his midterm...

The few quickly be a horde as people tried help them, but got bitten.

As the horde grew, stress increased... and as stress increased, the more people's virus would mutate and turn them.

There were 60 thousand in just a 3 hours.

The military was brought in, but they were little help. Soon their operation was turn from extermination, to suppression... from suppression, to bid time.

While the military was keeping the zombies in the city, the government was making a way to keep the zombies in Austin. They put up street blockades. Then they built shabby walls of steel, wood and tin around the city. Then a mile out form that, they made a massive 200 meter tall solid wall around the whole city.

The military was told to evacuate, and they closed the walls. Hoping to wait this out, and take Austin after the walkers were worn out and finally resting.

Unfortunately, one of the soldiers that evacuated Austin had a "one night stand" with a woman from Austin. He unknowingly got the virus, and took it out of the city when he left. Thanks to him the virus quickly spread throughout Texas. The U.S. quickly followed along with every major country in the world, including the one that made the virus.

Its been 1 year, and only about 1 million people are left. With only a few "safe towns" in every country.

This is your story, inside sealed off Austin... aka... Z City...
