Worldview: Wasteland Mechanical Age
- Era background: In 2249 AD, human civilization collapsed after the "Mechanical Rebellion", and the surface of the earth was covered with rusty mechanical debris. The surviving humans hid in the underground "Ark City" and survived by recycling mechanical parts from the old era.
- Core conflict: Ark City is depleted of energy and needs to go to the "Mechanical Core Area" on the surface to seize the energy core; at the same time, the remaining mechanical lords (AI with self-awareness) regard humans as "viruses" and continue to encircle and suppress survivors.
