Underground

Underground is an action-adventure survival and exploration game in which you control Evee, a biologist with military training. Wearing a Suit-tech armor that protects her from toxic and hostile environments, she enters Underground 01 of Ricks Cross to assess the refuge and confront the threats inside. With the atmosphere outside made chemically toxic, the underground’s remaining oxygen and fresh water may be vital to human survival.

The underground system

Built to shelter hundreds or thousands of people through a chemical-biological war, underground refuges are isolated, self-sustaining havens. Each is powered by aortic crystals, metritic energy crystals that sustain its synthetic biomes and manage the system’s behavior and defenses. The system is designed to maintain the biomes’ balance and eliminate biological invasions and other threats.

The war left many undergrounds uninhabitable and hostile, while only a few partially withstood the bombardments. Underground 01, in Ricks Cross, Houstonian-USD, is the largest refuge built and apparently suffered the least damage. Evee’s mission there may be humanity’s last chance of salvation.

Explore and survive

You guide Evee through synthetic environments including forest greenhouses, desert areas, residential condominiums and maritime areas. She faces biological and mechanical enemies created to protect the refuge, as well as creatures transformed by the chemically altered atmosphere after the war.

Evee’s presence is unrecorded, so the system identifies her as a Class 5 threat and moves to destroy her. Her objective is to destroy the crystals and eliminate the threats within the refuge.
