Underground: Bunker Survival

Build, Manage, Keep Them Alive

USD 0.29 · 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.

"Ration days" can now also be completed with rations in storage — within reach for large shelters. Arrivals at the gate. Every ring now has a label, and generous shelters get a "Generosity" ring. Incidents. Decision buttons are brighter and easy to spot. Leaderboard. Support for the game is now marked with hearts. Guidebook. "Mini-games: where to find them and what they give" is rewritten: which room, which button, and what each game brings. Radio. When a new version comes out, HQ sends a radiogram to your bell. Hold fast, Overseer.
