About Underground: Bunker Survival
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.
What's New
DIRECTIVE 1.32 — BULLETIN FOR ALL POSTS Reserves first, shutdowns last. During an energy shortage, the grid now draws on what you've stored first: the reserve and Battery room charge above the emergency level. Compartments go dark only when the reserve covers less than a day of shortage, and come back once it covers a day and a half. The Battery room's Auto shutdown follows the same rule. The Energy info shows how long until shutdowns begin. Power priorities for every compartment. The list now includes every built energy consumer: the Psychology compartment, the Children's zone and two dozen more. Storage remembers your decisions. Fortify the storage, audits, guards posted after thefts and other choices now stay in the Storage stats. The bonus fades by 1 point a day and caps at +30. Storage Risks now show Fire safety and how much fuel adds to fire risk. Disposing of stock now simply frees up space and no longer adds order or sanitation. Investigations in small bunkers. A case now comes together with just one or two residents. With a single suspect, it's Case closed. With no one to suspect, HQ will say so. Upgrade labels. Benefits are shown in green and costs in orange, and every number carries the right sign. Noise insulation lowers stress by 2 a day, Warm zone takes 1 energy a day, and the Threat analysis module lowers expedition risk. All residents. Each card now shows a resident's worst reading (fatigue, stress or hunger), coloured by severity, so you can see at a gl
