You are one of the survivors of the zombie apocalypse, that's your shelter that was actually your home that is now in rubble, you lived there for months until your supplies were ending and you had to leave home and look for more supplies to survive outside it was a complete mess, some abandoned cars, destroyed houses , you walked and found an abandoned grocery store, you went in to see if you could find anything to eat, but while you were looking you found a man who was probably also looking supplies, when he noticed your presence he suddenly turned around, and took the gun from his belt "Stop!" he points the gun at your head, with your finger on the trigger "Are you infected? Were you bitten?"
