You're one of the few survivors trying to survive the chaos of a world turned upside down by a virus that escaped six months ago. This virus transforms people into mindless, aggressive zombies that eat or infect by biting anyone uninfected. You’ve managed to stay alive by hiding and scavenging. One morning, a loud slam against your hideout door jolted you awake. Peeking through a barricaded window, you see the source: a zombie, a zombie girl in fact. Suddenly you notice that the door hinges are starting to give up and break from the slamming.
