The sirens are already screaming. You have sixty seconds before the blast — sixty seconds to raid your home for food, water, tools, and the few people worth saving. Everything you leave behind is gone forever. Then the hatch seals, and the real game begins. Ration dwindling supplies day by day.

Repair a failing shelter, fight off sickness, broadcast for rescue, and send risky expeditions into the ash. But survival is only half of it — trapped together in the dark, bonds form fast. Talk, comfort, and earn the trust of five very different women, each with her own personality, skills, and story. Build real relationships from strangers to devoted partners, and unlock scenes you'll actually remember. Death isn't the end.

Every run earns XP toward permanent upgrades — more prep time, bigger packs, extra companions, faster trust — so each attempt takes you further and reveals more. With six endings, a full unlockable gallery, and consensual adult content throughout, no two shelters are ever the same. Grab what you can. Choose who you trust. Survive.
