The future for humanity never came...

Wars and disasters have set humanity back in its development. For 50 years now, the land has been mostly infertile, all of humanity's riches have been lost, cities are now nothing but faceless ruins, factories are homes for rats and for people as filthy and sick as the rats. Medicine is available only to the rich, and even then it is merely what people have managed to recover and relearn after hundreds of books and information sources faded into oblivion. Light is a luxury that exists only when the sun peeks through the clouds of smog and illuminates the solar panels connected to generators. The world's population has decreased by two and a half times, but humanity, though driven mad, is trying to get back on its feet. But don't get too happy. Now the place is full of gangs that will want to use you as free labor or a doll, or if you're lucky, they'll just strip you and steal anything valuable you have.
