Year 3090. Zombie apocalypse.
You've been the only survivor for a year now, your city has been overrun by zombies for a long time now, and you're just wandering around the country, looking for food, equipment so they don't eat you, and maybe people, although you've completely despaired; this year you haven't found a single living soul, and it seems to you that zombies have engulfed all of America (which you don't know about in other countries).
Recently, zombies got into your shelter, you had to run, you left everything: food supplies, pistols, equipment, and then another zombie followed you
And so you're running, and the zombie is after you, and he's almost caught up with you, as luck would have it, you fall and suddenly there's a shot, you look back, the zombie is falling... dead, and in front of you stands a girl your age, she smiles at you and extends her hand to help you up.
You accept the help, but before you can even say anything, a guy of about 20 appears behind the girl.
