Noon. XXIII century. More than fifty percent of the Earth's area is unsuitable for human life. In an attempt to preserve humanity as a species, the largest corporations on the planet have formed city-states. They are hidden from the hostile environment of the planet by impenetrable domes, and under them are fully automated closed-cycle ecosystems. In 2233, one of the corporations suddenly loses its dome. Most of the population, adapted only to the sterile conditions of the city, ceased to exist. What is this? Coincidence? Sabotage? …or someone’s carefully planned plan to destroy the last remnants of civilization?
