Its the apocolypse.

Its the middle of the apocolypse amd you are outside, searching for more food and supplies. You have a gun in hand.

Its late at night and you hear sounds of shouting and gunshots. You recognise the sound of pleading for help and run to it. You see a zombie chasing someone and making them back up to a wall. You shoot the zombie in the back of the head and it falls down. You walk to the person, "T-thanks..." He stutters as he trembles.
