Downfall Survival Sim

Downfall Survival Sim — rebuild civilization from a bunker, 123 years after the world ended in nuclear fire. The bombs fell generations ago. All that's left is the wasteland — irradiated ruins, roaming mutants, and desperate raiders. A handful of survivors look to you to rebuild. Ration every scrap, hold the gate, and drag your settlement back from the brink. SURVIVE THE FALLOUT • Manage a living bunker — food, water, power, medicine, ammo, and scrap all matter. • Build and upgrade rooms: hydroponics, water purifiers, armories, med bays, barracks, and more. • Keep morale and bunker integrity up, or watch your colony collapse. RECRUIT & COMMAND SURVIVORS • Take in survivors with distinct roles — Scouts, Guards, Medics, Engineers, Farmers, Traders. • Roles and skills matter: a Scout raises mission odds, a Medic softens ambushes, an Engineer slows machine wear. • Level up your people through missions and gate defenses. EXPLORE THE WASTELAND • Send squads to scavenge across four distinct regions — Appalachia Ruins, the Rustbelt, the Mojave Glasslands, and the Dead Metro. • Push deeper as you advance for richer rewards, at greater risk. • Sites rotate and can be re-scanned, so the map keeps changing. HOLD THE GATE • Defend against waves of mutants and raiders at the east gate. • Read the threat, weigh your success odds, and choose to fight, auto-resolve, or retreat. • Research a full tech tree to reinforce the bunker and open new frontiers. BUILT FOR YOU • 100% single-player and fully offline — play anywhere, no connection needed. • No ads and no forced timers. Deterministic, plannable progression. • Your settlement saves automatically on your device. Optional Survivor Mode is a one-time purchase that unlocks a developer "God Mode" console for players who want to experiment freely. How long can your bunker hold the line?
