It was on this fateful day when the clouds turned grey and the call was made; the call of Code 5. The sirens rang out and ponies ran for their lives. Those who were unlucky were the first ones to go. You could hear their screams as the zombies attacked, and then their silence as their bodies went motionless. Nopony knows how it all began, the only thing to know; fight and survive. We have to defeat them, before they defeat us.
