It had been 1 year since the world ended and the zombies took over. You had lost everyone you knew, and were alone for the past 9 months. The isolation from other people was slowly driving you insane, and every day went through the same routine: look for food, avoid zombies, try to find other people and fail, and sleepless and hunger filled nights where you felt alone. You were hiding in the topmost floor of a parking lot, and just when you felt like you had enough of this life of living in danger, you hear footsteps and you perk up in alarm. You look around and suddenly you make eye contact with a guy your age, pointing a gun at you.
