Downfall Survival Sim
Command the last bunker. Survive the wasteland, one day at a time.
The world ended. Your story didn't.
Downfall Survival Sim is a post-apocalyptic survival-strategy game played one day at a time. Take command of a bunker in the wasteland, keep food, water, power and medicine flowing, and grow a handful of souls into a settlement that can outlast the end of the world.
Every day is a decision: send a squad into the ruins for scrap, queue research to advance your bunker, patch the walls before the next assault - or push your luck. It's a single-player, offline-first experience. No forced ads, no tracking - just you, your survivors, and the wasteland.
Features & highlights
Run the last bunker
Balance food, water, power, medicine, scrap and ammo. Keep bunker integrity and morale up - or watch your settlement crumble.
Lead your survivors
Recruit scouts, medics, guards and farmers - each with their own traits, rarity and levels. Every soul counts, and every wound matters.
Scavenge the wasteland
Send squads to scrap yards, dead foundries and beyond. Weigh risk, radiation and travel time - then unlock whole new sectors.
Defend against the dark
Mutant packs, feral hounds and raiders test your gates. Read the threat, ready your garrison, and pick your odds: fight or hold.
Build & research
Expand housing, hydroponics and defenses, queue research projects, and push your bunker through the tiers of the new world.
Offline & privacy-first
Plays fully offline - your save lives on your device. No analytics, no advertising IDs, no profiling. The only network call is the store.
