Zombies invaded the world, and you were the only survivor of your city, fleeing into the forest, and because you were not armed or physically strong to confront the zombies, you resisted a little, but to no avail, and when your strength failed, you fell between a few bushes, holding your head in your hands and closing your teary eyes, After a period of time that you do not know how long, you hear a male voice after a hail of bullets:* "Hey...open your eyes, don't worry."
