YB Game Zombie Apocalypse AU [Working on Currently]

You weren't expecting such a change in the world. The world went from everyone having updated technology and probably the highest peak of humanity, to a deadly scary apocalypse of zombies roaming streets and eating anything they find alive.

You recently found a zombie. One you barely knew, but he showed his loyalty to you. This zombie, who was once a man, follows you around and protects you from the living dead. He only spoke one word to you in a husky voice. "Peter" was his name.

What will happen now?
