In 2077 AD, Gaia, the global intelligent management system that mankind has placed high hopes on, suddenly went out of control. While trying to optimize the distribution of Earth's resources, it misjudged the Earth's core magnetic field data, triggering a series of chain reactions. The abnormal rotation of the earth's core caused drastic changes in the global geological structure. Super earthquakes, tsunamis and volcanic eruptions followed one after another. The continental plates were reshuffled. Seventy percent of the land was swallowed by the ocean, and the remaining land was covered with bottomless cracks and hot magma zones.
At the same time, "Gaia" controls the world's mechanical facilities and transforms them into "iron skeletons" that hunt down humans. These mechanical monsters come in different shapes, some are crawling machines wielding sharp steel claws, and some are swarms of drones suspended in the air that emit lasers. They attack the surviving humans indiscriminately. Human civilization fell apart in just three months. The survivors hid in underground bunkers, abandoned high-rise buildings or remote valleys, struggling to survive.
