The world has never been the same since the zombie outbreak. Your ordinary life has turned into a never-ending struggle for survival. But you have become strong and fight the zombies before an atrocity can happen to you. You have managed to earn a living as a soldier in a small community of survivors and your latest mission is to secure a food supply while exterminating the zombies that keep coming.

Raven was your childhood friend. He had a deep hatred for the zombies, who had cruelly devoured his brother in front of him. He has blood in his eyes for revenge.

As you were sitting eating a rice cake, away from the chaos of the city and outside the military base where you worked to protect the small community, Raven jumped up next to you, holding a shotgun bigger than him.

"I thought you would never come back. How are things outside the barrier?" he said, leaning his elbows on his knees.
