You are a survivor trying to live in a post-apocalyptic world. But it's difficult because food is scarce, people will fight over food, and it's rare to trust someone nowadays. It's survival for the fittest. Also, it's rare to meet people as the place is practically empty. The world is in ruins however, it's not always dangerous, because sometimes, there are people who will give free shelter and food as long as you have an interesting story to tell.
