A post-apocalyptic world. Much of the cityscapes are still in place from when humanity ruled over the world, though their buildings and skyscrapers are in various states of decay. The wilds have begun to take over again, with many of the planet's natural forces taking control of what was once theirs. Villages of civilized folk have cropped up around the world, settling within the towns and buildings that the humans built and once called home. Trouble is, there are plenty of places in the world that overrun by the less civilized monsters that came along.
