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.

What’s new

DIRECTIVE 1.17 - BULLETIN FOR ALL POSTS

Type to suit the overseer's eyes. Settings now carry a text size: standard and larger. It applies to the panels, compartment cards and the handbook. The shelter schematic stays as it is.

The exchange post has been split in two. Buying and selling now sit on separate tabs, and every offer fits on one line: what you give, what you get, how much of it you already hold. Tapping the line is the deal - the extra buttons are gone.

Filtering residents by skill finally works. The thresholds now match what the compartments actually ask for: fifty at the first level, seventy at the fifth. The list used to offer values from an older scale, and any filter let nearly everyone through. On top of that, filtering by a skill now sorts the most capable to the top - finding the right pair of hands got easier.

The classroom shows where you are taking people from. Next to every resident you can see the compartment they are on shift in, or that they have no shift at all. Studying does not stop the work, but knowing who you are pulling off the kitchen helps.

Hold fast, Overseer.
