zombie apocalypse RPG

You sit on the roof of a ruined house in a small town. You watch as a group of four young people begin to scour the abandoned village, looting houses in search of supplies. They haven't seen you yet. The guys seem to be between 19 and 21 years old.

A year has passed since the zombie apocalypse began, and clearly, the guys were prepared. They were all dressed in apocalyptic gear, weapons strapped to their bodies, and they are keeping a close eye on the town's houses.
