Underground: Bunker Survival

Build, Manage, Keep Them Alive

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

The world has fallen. You are the last hope for those knocking at your gates. Underground is a deep bunker-management sim where every decision echoes through your food, water, power — and your people's spirits. Build compartments across three floors, take in survivors at the airlock, keep your resources in balance, and don't let the bunker go dark. What's waiting for you: • A living bunker — 40+ compartment types: generator room, farm, med bay, laboratory, armory, district map, the old metro and more. Every room works differently and demands your attention. • Resources with consequences — power, water, food, air, parts, fuel. Run out of water and newcomers will walk right past your gates. Overheat the generator and an accident is only a matter of time. • People, not numbers — every resident has skills, health, stress and relationships. Quarrels, illness, theft, panic — incidents won't wait: you have limited time to solve a problem before it gets worse. • Arrivals at the gate — survivors keep coming to the airlock. Let them in, turn them away, or send them off with rations? Your bunker's reputation decides who shows up tomorrow. • Your own path — fortress, radio contact, autonomy, science, evacuation or a return to the surface. Goals will show you where to grow next. • The metro and recon — explore the tunnels, gather loot, trade with friends and fight off threats in the corridors. • Mini-games that matter — harvest crops, repair equipment, calm a panic: quick games earn resources and change how events end. • Friends in the game — add friends, meet their survivors at your gates, exchange resources and earn bonuses for playing together. • Play at your own pace — minimize the app and time in the bunker stops. Come back and pick up right where you left off. Who this game is for: If you love Fallout Shelter, This War of Mine, or management games with personality — this one is full of "what if I try it this way?" moments. Not a five-minute arcade, but a bunker that grows with you. Download. Open the airlock. Decide who gets in first.

DIRECTIVE 1.10 — ALL-STATIONS BULLETIN The Office of Public Order reports. Rumors about the old command bunker no longer spread unchecked: while trust risk stays low, the community doesn't lose a single point of cohesion, and the whispers die down on their own once incidents are resolved. A tight-knit colony can now live with a secret beneath the floor — without coming apart. The medical service has sorted out its admission logs. Every med bay used to think it was the shelter's only hospital: all of them fought over the same critical patients while everyone else waited in every line at once. A patient is now registered in exactly one bay, queues are split between hospitals, and several med bays finally treat several times more people — not the same five. Medicine use has dropped accordingly. The auto-med stations, the psychologist and the recreation room follow the same order. The security office and the perimeter have been elevated in standing. The sharper the watch details and the better camouflaged the traps, the harder the shelter is to find. Generator halls have been given extra lining: we're much harder to hear from above. Stealth is no longer a luxury of the early days. The recycling plant has opened a new line. Replacement cartridges for water and air filters are now assembled from tech waste — slowly, but with our own hands. The exchange office is no longer the only way. The med bay reports new arrivals on the way. More children are being born under our roof: couples commit sooner, mothers recover faster, and two mothers-to-be can now be under care at the same time. The robot bay has been cleared for teardown. Machines past their prime can be stripped for parts and scrap — take a robot off shift and rebuild your fleet for the tasks of the day. The psychologist's office and the recreation room now run an honest clock. Session hours don't burn away while the compartment is dark, and residents under the heaviest strain get a follow-up appointment without waiting in line. The boards show the exact time to discharge. The filtration units now count everyone. Maximum occupancy is tallied across all working filters — the panicked "there are too many of us" bulletins have been discontinued. The uplink to the surface has been reinforced. If headquarters goes silent, a new shelter is founded without delay — we'll register your call sign once the airwaves come back to life. Waits for a response have been cut to a quarter. The handbook has grown. The engineering lab and the robot bay now have proper pages: what projects are for, what the synergies do, and why eight hours of sleep is not a whim. Hold the line, Overseer. The shelter runs deeper — and we stand closer.
