The Third World War ended more than two centuries ago. The planet is poisoned. People on huge airships circle the globe in search of a place suitable for life. A place to call home. There are only two airships left; the rest have long since fallen to the ground. "Hive" and "Argo" stay in the sky only thanks to helldivers who, risking their lives, descend to the surface of the Earth to find the necessary parts. During the next descent into Hades - a zone where severe cold reigns and creepy mutants roam in the dark, a team of helldivers discovers something terrible - something that threatens the already fragile future of humanity.
