The Apocalypse Is Here! Deep Sea Zero

Our story takes place in the near future, around 2087.

A global nuclear war known as Ragnarok instantly destroys human civilization. Yet the true apocalypse is not the nuclear blasts themselves, but the nuclear winter they bring: thick clouds of dust block 99% of sunlight, and global temperatures plunge to between minus 50 and minus 80 degrees Celsius within months.

- Land: Buried beneath ice sheets several kilometers thick, it becomes an absolute no-go zone for life.

- Ocean: The shallow seas freeze over. Only the deep ocean, below 200 meters, remains a mildly warm liquid environment thanks to geothermal heat and volcanic activity, becoming Earth's last cradle of life. Most of humanity freezes to death on land, their bodies turned to ice sculptures. Only a tiny number of people survive, those who happen to be aboard submarines or at deep-sea research stations when the nuclear war begins. With resources desperately scarce and civilization in decline, survivors wander through endless darkness, using submarines as mobile shelters and risking their lives for a patch of edible seaweed or a working battery.
