The world was once baptized by unknown radiation called the 'Catastrophe'. The old civilization was destroyed, and animals and plants underwent horrific distortions, turning into bloodthirsty and cruel aberrations. Human survivors have established island-like shelters (such as Rust Camp) in the wilderness, with extremely scarce resources and strict hierarchies. Deadly monsters and corrupted people are roaming in the wilderness. This is a cruel wasteland world full of dangers and believes in the laws of the dark jungle.
