The fifth floor. Below the fourth floor lies the blast door of an old shelter: sector 3, a laboratory sealed from the inside. Opening the door takes 800 parts and 10 tools. Then the sector has to be reclaimed, twenty-two rooms, one at a time.
Teams. Every room has its own requirements: how many people, which skills, what health. The game picks a team for you, and you can swap anyone. The team really leaves: their posts stand empty while they're down there, and they need rest when they're back.
Infection. It still lingers in the sector. Each room has its own risk, form of illness and treatment time. The sick go to quarantine or the med bay. Untreated, a sick resident can infect a neighbour.
Team records. In every room the team finds what was there and what happened. The reports piece together the story of the shift that served in the sector: nine personal cards are waiting for names. The laboratory comes last, behind an unpowered blast door.
Memorial room. The names of the fallen go on the wall. With the room, the shelter bears its losses more easily, and a minute of silence once a day lifts morale.
Trading post. Caravans come to the shelter, stay for a while and move on. While they're at the gate you can trade resources, and water goes straight from and into the tank.
HQ awards. A new "Sector 3" goal and "The Nine" award. Award badges are now HQ brass tokens, both in the game and in Game Center.
Leaderboard. Points for reclaimed rooms and the laboratory. More than five support hearts now show as five plus "+N".

Snake. The board is bigger on Very fast. At high speeds the snake pauses for a moment at a wall, so your turn still lands. The control buttons are bigger.
Classroom. Search residents by first or last name — the student you need is a couple of letters away.
Goals. "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.

Rooms. The room window now has ‹ › arrows in its header: jump to the next room of the same type — kitchen, generator room, residential — without closing the window. The tab stays the same: start rations in one kitchen, tap the arrow, start them in the next.
Drones. Modules are installed from their own window: you see the full price, radio components and rare components included, and exactly what's missing.
Classroom. A new "Off shift" filter shows only residents who aren't working anywhere; it combines with the skill filters. With a skill selected, residents who already have it at 100 are left out — there's nothing left to teach them.
Thanks to the Overseers who sent in these reports.

Snake. Pick a speed before you start: Steady, Fast or Very fast. The faster the snake, the more you collect — up to ×1.5. It speeds up with every pickup and waits a second before moving, so you can get your bearings.
Number hunt. You now get 20 seconds per number instead of 15.
Incidents. Decision buttons now match the rest of the game.
Friends. If a friend request can't be accepted because the friends list is full, the game tells you so and offers to decline it. Gifts show what's left for the day: how many sends and how much you can still pass on.
Store. The store button is now right on the map, under the Chronicle. You can support the game more than once: each time earns a star in the leaderboard. If you supported us before, your first star is already there. Thank you.
Language. Radio frequency names and store items now follow the language chosen in the game.

Происшествия. Кнопки решений стали крупнее. После выбора в журнале появляется итог: что сделано и что изменилось в запасах.
Холода. Мороз теперь поднимает расход энергии только в отсеках, которые нужно греть: жилых, детской, ферме и теплице. Мораль от холода падает, только когда энергии не хватает.
Награды штаба. «Выросли под землёй» засчитывается и за детей, выросших до обновления. «Все в сборе» раньше было не получить: у ворот не собирается больше 8 человек. Теперь награда — за полную очередь из 8 человек, принятую разом, когда в убежище уже 20 жителей и всем хватает коек. В справочнике — ответы про награды штаба и новые советы.
iPhone Duo. Игра подстраивается под складной экран: окна отсеков меняют ширину при раскрытии, кнопки стоят у края, мини-игры — по центру. На iPad мини-игры тоже стали аккуратнее.

HQ Awards. Shelter goals now include HQ Awards — 25 of them, three hidden. For each one, HQ sends a radiogram and parts. The awards also appear in Game Center. Anything your shelter has already earned arrives right after the update in a single radiogram.
Call sign. You can now change your shelter's name in Settings. It's free, once a week.
Rooms. In seven rooms, part of the daily progress was lost by the end of the turn: the Surface Restoration Center, Central AI, Command Center, Children's Zone, Classroom, Psychology Room and Training Zone. Now it counts in full — the surface maps no longer stand still.
Logs. Event entries in room logs no longer go missing.

Parts ledger. HQ now keeps a ledger of parts. Tap parts in the top bar. The card shows how many came in and went out today and yesterday. It also lists what the parts were spent on and where they came from: rooms, incidents, construction, upgrades, day skips, exchange. And it shows which rooms make or use parts on their own every day.
Daily summary. When a new day begins, one line arrives in the bell: how many parts came in and went out over the past day, and what took the most.

Смены. При назначении в любой отсек, включая пост у шлюза, у каждого кандидата видны навыки, которые нужны этому отсеку. Самые подходящие стоят в начале списка, а лучший отмечен золотой звездой. Искать нужного человека по именам больше не придётся.
Жители. Возраст пишется как положено: «1 год», «3 года», «25 лет».
Детская зона. Подсказка различает, когда детей в убежище пока нет и когда все дети уже зачислены.
Звук. После звонка или сворачивания игры звук возвращается плавнее.

HQ parcel. Every day HQ sends a parcel: parts or a specialist at your gate. The longer your streak, the more generous it gets. You can see the whole chain ahead.
Weather up top. From day four, dust storms, cold snaps and clear days come and go, each lasting several days. In a storm fewer people reach the gate, and drones and scouts take longer. In a cold snap energy use goes up. On clear days more people arrive and residents cheer up. An icon next to the clock shows the weather and how long it will last.
HQ task of the week. Once a week HQ sets a task: admit people, build rooms, resolve incidents, heal residents. The reward is parts and a specialist at your gate. The task sits at the top of Goals.
Alliance. Ladle, Beacon-2 and Laundry come on the radio asking for help: a medic, an engineer, a guard, water, food, medicine. Lend a resident for two days and they come back with a reward. Share supplies and the allies send cargo in return. The alliance remembers both help and refusals. Answer them in the radio room.
Generator room. New mini-game, Wiring repair: rotate the wire pieces until the current reaches every lamp. The generator wears less, and the grid gets energy.
Airlock. The Admit all button lets the gate queue in at once, as many as the airlock can pass today.

Chronicle. It now has its own button on the map, above the guide book. It holds the story papers and every radiogram from HQ, so you can reread them at any time.
Alerts. Every event shows its day and time. You can remove lines one at a time.
Residents. You can filter the list by room. You can expel a resident from the shelter right from their card. When enrolling in the Training zone, you can see each candidate’s skills.
Rooms. You can move a room to an empty cell for 10 parts. Power priorities have their own Power tab in the generator room and the geothermal node. Every mode shows exactly what it changes. Training programs show which skill they build and how long they take.
Greenhouse. The plants now produce air, helping your filters.
Airlock. The airlock card shows how likely intruders are each day and what lowers that chance.
Construction. The construction panel has a close button and disappears on its own once the room is ready.
Friends. The section is more reliable. Your nickname and your visibility in “Looking for friends” save properly, and you can see when a request is being sent.
iPad. Room cards now fit the larger screen.
Guide. Clearer explanation of how food and rations work. Hints in the old metro are tidier.

- 📦Underground: Bunker Survival updated to version 1.34DIRECTIVE 1.34 — BULLETIN FOR ALL POSTS
Children's zone. Enrolled teenagers stay under "Children in the zone" and keep growing up until their term ends. Supervision places go to adults only: children don't take them, and a supervisor under heavy stress stays on supervision. Taking a child out of the zone ends their growing up. Teenagers currently listed under "Supervision" will return to their place on their own after the update, with no need to enroll them again.
Resident relationships. "Unknown" lines no longer appear on a resident's card. Ties to people who left the shelter or never made it through the airlock are cleared automatically, in older saves too.
Old network sorties. Sortie messages now match the team: one scout or a pair is named correctly.
Old metro. Enemies from the metro come out on the metro's floor, not deep inside the bunker. A metro guard returns to their post after a course in the Classroom or the Training zone.
Clearer English. Rooms are called rooms throughout the shelter, room titles and filters read more naturally, staff counts read cleanly, and mode descriptions no longer run sentences together.

Silence in switched-off compartments. A paused compartment no longer reports on work that isn't happening. This covers the Training zone when Suspended, the Generator room, Air filter and Water node when switched off, the Laboratory on Waiting, and the Sealed sector when Isolated. A closed Airlock no longer asks you to close the entrance.
No more vicious circle in the Generator room. Overheating now happens only to a running generator. A switched-off one no longer reports overheating several times a day while it cools down.
The shooting range only where there is one. Ammo consumption at the range happens only once a Shooting range is installed in the Training zone. Other drill events also come only when they fit: injuries when there are trainees, an accident on the course when a scouting programme is running.
Old metro labyrinth. The multiplier for collecting every part is the reward for fully studying a branch for the first time. Repeat runs through a studied branch pay one part per find. The counter in the labyrinth shows what the current run will pay.
Storage. Rare components no longer go below zero when the farm puts a rare substrate to use.

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 glance who needs rest.
Departures and the Med bay. A resident who leaves during a crisis is now cleared from every post: the Classroom, the Med bay, the Airlock and their partnership. Only someone who was on their feet can come back as the Wounded scout, so no one ends up in the Med bay queue twice.
A month of trials. Before release, HQ ran several bunkers, from a fresh start to one packed to the brim, through a month of game life.

Rearrange your rooms. You can now reshape the bunker to suit you. Every finished room has a new Rearrange section: pick another room and the two swap places for 20 parts. Residents, upgrades and stock move along with the room.
Radio room and Scouting HQ work together. Every intercepted message now has a Log decryption button. Decode it yourself, pick what it says, and a correct decryption goes into the Scouting HQ intel for free. There you can see where the fragment sits, what it holds and whether it is waiting for a scout, and those cells on the assembled map carry an antenna mark.
Fuel in plain sight. The top bar now shows your fuel stock and daily burn right next to energy. Tap it for a guide page: who burns it, where it comes from and how much the storage holds.
Back along the trail. The old metro labyrinth has a new Back button: the scout retraces the trail on their own to the previous fork or the entrance.
Class results. When a course ends, the log names every student and how much their skill grew.
No accidental trades. Every deal at the exchange office now asks for confirmation on its own card. And you can sell surplus even with a full storage: the goods leave and free up room for the parts.
While you're busy. With the labyrinth or another screen open, the bunker keeps living, but new incidents and intrusions no longer pile up on you all at once when you return.

Смена режима — только по подтверждению. Переключатели режимов во всех отсеках и в шлюзе теперь спрашивают, прежде чем сработать: карточка показывает отсек и новый режим и напоминает, что следующая смена будет только на следующий игровой день. Случайное касание при прокрутке больше не тратит единственную смену за сутки.
Приток к воротам: видно слабое место. Блок притока на карте теперь называет фактор, который сильнее всего сдерживает приход людей, и его оценку. Если стресс жителей высок, заметка о стабильности говорит об этом прямо.
Справка про стабильность. В справке появился разбор, из чего складывается стабильность убежища и почему она меняется ступенями, а список признаков привлекательности дополнен.
Новая игра. Перед началом новой игры штаб предупреждает: детали и запасы, в том числе купленные в магазине, остаются в старом сохранении.

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.

The fifth floor. Below the fourth floor lies the blast door of an old shelter: sector 3, a laboratory sealed from the inside. Opening the door takes 800 parts and 10 tools. Then the sector has to be reclaimed, twenty-two rooms, one at a time.
Teams. Every room has its own requirements: how many people, which skills, what health. The game picks a team for you, and you can swap anyone. The team really leaves: their posts stand empty while they're down there, and they need rest when they're back.
Infection. It still lingers in the sector. Each room has its own risk, form of illness and treatment time. The sick go to quarantine or the med bay. Untreated, a sick resident can infect a neighbour.
Team records. In every room the team finds what was there and what happened. The reports piece together the story of the shift that served in the sector: nine personal cards are waiting for names. The laboratory comes last, behind an unpowered blast door.
Memorial room. The names of the fallen go on the wall. With the room, the shelter bears its losses more easily, and a minute of silence once a day lifts morale.
Trading post. Caravans come to the shelter, stay for a while and move on. While they're at the gate you can trade resources, and water goes straight from and into the tank.
HQ awards. A new "Sector 3" goal and "The Nine" award. Award badges are now HQ brass tokens, both in the game and in Game Center.
Leaderboard. Points for reclaimed rooms and the laboratory. More than five support hearts now show as five plus "+N".
Hold fast, Overseer.

Snake. The board is bigger on Very fast. At high speeds the snake pauses for a moment at a wall, so your turn still lands. The control buttons are bigger.
Classroom. Search residents by first or last name — the student you need is a couple of letters away.
Goals. "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.

Rooms. The room window now has ‹ › arrows in its header: jump to the next room of the same type — kitchen, generator room, residential — without closing the window. The tab stays the same: start rations in one kitchen, tap the arrow, start them in the next.
Drones. Modules are installed from their own window: you see the full price, radio components and rare components included, and exactly what's missing.
Classroom. A new "Off shift" filter shows only residents who aren't working anywhere; it combines with the skill filters. With a skill selected, residents who already have it at 100 are left out — there's nothing left to teach them.
Thanks to the Overseers who sent in these reports.
Hold fast, Overseer.
