Ice Apocalypse

The world is a blank white canvas. Ice claws into the skyscrapers like frozen bones; the wind howls like a wounded beast, piercing through your tattered jacket. You scramble through the ruins of an old 24-hour convenience store, clutching a half-empty can of beans in your hands—your last food for the next 3 days. Your breath forms tiny clouds that vanish into the eternal cold. Mutant parasites also live here; they infect the remaining plants and animals. It is a parasitic species of fungi that takes various forms. The only way to survive is to hide, either in caves or by burrowing somewhere very deep.
