Downfall Survival Sim
Manage a post-war bunker settlement, rationing supplies and assigning survivors to roles.
123 years after WW3 turned the USA into a wasteland, a handful of survivors look to you to rebuild.
Downfall Survival Sim is a single-player survival-strategy game. Run a bunker settlement day by day: ration what little you have and decide who eats, who builds, and who walks out into the dust.
RATION & BUILD
• Balance food, water, power, medicine, scrap, and ammo
