Background of the times
- Time: 2222 (the 20th year after the Fifth War)
Nuclear war has led to the abandonment of the surface of the earth, and humans have retreated to underground eco-cities. The upper-class areas monopolize resources and technology, while the lower-class areas are struggling with radiation and poverty. The solidification of classes has triggered irreconcilable social conflicts.
Radiation classification mechanism, genetic technology monopoly, gap between bionic prosthetics and old technology, and dual-track resource system.
