Introduction

When the dead first started rising and attacking the living, reports were largely suppressed out of fear that the truth would lead to widespread panic.

As a result, most citizens were completely unaware of the horrific incidents happening around them. But what started out with a few isolated cases quickly spread into a full-scale epidemic - an epidemic that couldn't be ignored or covered up.

Quarantines were established and evacuation orders were issued, but the infection spread spread faster than the government and military could respond.

Soon, entire cities and regions were overrun with the infected. The root cause of the outbreak appears to be a virus or infection that causes the death and reanimation of affected individuals.

Upon reanimation, corpses retain the same motor skills as a normal living human but lack all cognitive functions and reasoning.

As a result, the undead seem to have only one purpose: to attack and kill the living. There is no cure for the infection. The only hope is to escape it and the thousands of zombies who have succumbed to it.
