## Description

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
• Upgrade your bunker modules — hydro farms, water reclaimers, barracks, workshops
• Keep integrity and morale up, or watch the colony collapse

RECRUIT SURVIVORS
• Scouts, guards, medics, engineers, farmers, and traders — each with their own skills and rarities
• Survivors level up on missions. Keep them healed and their morale high
• Optional permadeath for the brave

EXPLORE THE WASTELAND
• Send squads across four irradiated regions
• Scavenge ruins, rescue strangers, watch the radiation
• Trade with passing caravans

RESEARCH & DEFEND
• Unlock the full tech tree
• Hold the gate against mutant packs and raider bands
• Fight the battles yourself or auto-resolve them

Offline. No ads. No account. Your settlement
One optional purchase (Survivor Mode) unlocks a developer God-Mode cheat console for players who want to sandbox.

Built by XXI Online Games.
