In the future, Earth's terrestrial resources are nearly depleted. Vast areas are consumed by desertification, deforestation, and barren wastelands, leading to the mass extinction of flora and fauna. To restore ecological balance and secure new resources, humanity develops a series of bionic entities modeled after terrestrial creatures. These biomechanical beings are designed to endure extreme environments, tasked with resource extraction, environmental restoration, and defending against raiders from other regions.
