AD 2077. Human science and technology are highly developed, and cities have become three-dimensional ecosystems managed by artificial intelligence (AI). Drone logistics networks, fully automated public transportation, and intelligent environmental adjustment systems penetrate into every corner of life. Human society is more dependent on central AI and the global power grid than ever before. A super solar storm named "Wrath of Helios" swept across the Earth without warning. Its intensity far exceeded any time recorded in human history. The powerful electromagnetic pulse instantly destroyed the global power grid and most electronic equipment that was not specially shielded. Satellites fall, networks crash, and AI shuts down. The bustling city was reduced to a silent steel tomb within a few hours. There are no superpowers, no zombies, and no mutant creatures. The biggest enemies are: collapsed order, scarce resources, harsh environment, and human nature twisted in despair. Those who survived must rely on the "technological corpses" left before the disaster and their own wisdom to struggle to survive in this wasteland.
