Your Vault is under attack. Resources are low. Dwellers are panicking. Being an Overseer in Fallout Shelter is no easy job. I learned that the hard way in my first vault. But don’t worry – this Fallout Shelter guide will help you avoid those mistakes. Follow these tips and build a Vault that lasts. We cover everything from beginner basics to advanced strategies. Let’s get your Vault running strong!
Fallout Shelter Beginner Guide
Start slow and secure. In the beginning, your first priority is to stabilize resources. Here are some quick tips for new Overseers:
Keep Resources Green
Always keep your power, food, and water bars in the green. Low food means dwellers lose health, and low water causes radiation sickness. Never let these fall into the red.
Assign Dwellers Smartly
Match dwellers to rooms based on their best SPECIAL stats. High Strength goes to Power Generators, Agility to Diners, Perception to Water Treatment, etc. This maximizes production efficiency.
Arm Your Vault Early
Equip your dwellers with any weapons you find. Even a low-damage gun is better than nothing during a raider attack. Armed guards at the Vault door can save your whole Vault.
Use Rush Carefully
The Rush feature can earn extra caps and resources, but a failed rush triggers incidents (fires, radroach infestations). Only rush rooms when your dwellers are equipped and your success chance is reasonably high. A high average Luck stat in the room improves rush success.
Don’t Overexpand
Build new rooms only when you have enough dwellers to staff them and enough resources to support them. If you only have 4 workers for power, build a 2-wide power room (not a 3-wide) to avoid understaffing. Expanding too fast can lead to resource shortages and unhappy dwellers.
These beginner tips will set a strong foundation. Keep everyone fed, hydrated, and powered, and you’ll survive the early game without major crises.
Fallout Shelter Build Guide (Vault Layout & Rooms)
Design your Vault layout wisely. Always build production rooms in 3-room merges for maximum output and cost efficiency. Connect rooms of the same type so they merge into double or triple-size rooms – a triple produces more and upgrades cheaper than three singles. Also, plan your elevators in a convenient central shaft to let dwellers move around quickly.
Vault Layout
This vault uses a strategic “checkerboard” layout. Some rooms are separated by empty space or elevators, preventing disasters from spreading beyond one room.
If a fire or radroach incident occurs in an isolated room, it will burn out on its own without jumping to neighbors. Use this tactic to protect vulnerable dwellers in training or storage rooms.
Avoid leaving any room understaffed. A 3-wide room needs 6 dwellers for full efficiency – never run a triple room with just 2-3 people. If you lack staff, build smaller rooms until you have more trained dwellers. Similarly, upgrade rooms gradually. Don’t rush to level 3 rooms when your dwellers are still low-level and unarmed. Higher-level rooms spawn tougher disasters – a level 3 room can wipe out low-level dwellers during an incident.
A good rule of thumb: ensure your dwellers are about level 15 before upgrading a room to tier 2, and level 30+ before upgrading to tier 3. This way, they have the health and gear to survive any fires, radroaches, or worse.
Lastly, consider vault defense in your building plan. After 60 dwellers, Deathclaws will begin attacking your Vault. These are far stronger than raiders and will storm through the top floors. To prepare, create a “gauntlet” on your top level: fill those rooms with your strongest, highest-level dwellers, all armed with your best weapons.
Keep your weaker, low-level dwellers on lower floors. By the time threats reach them, they’ll hopefully be weakened or eliminated by your guards up top.
Fallout Shelter Stats Guide (SPECIAL Stats Explained)
Understanding SPECIAL stats is key to running an efficient Vault. Each stat corresponds to certain rooms and tasks. For example, Strength speeds up power production in Power Generators and Nuclear Reactors, while Agility speeds up food production in Diners and Gardens. The table below summarizes each SPECIAL stat and its main use:
SPECIAL Stat | Main Vault Use & Effects |
Strength (S) | Power generation rooms (Power Generators, Nuclear Plants). Increases power output speed. |
Perception (P) | Water production rooms (Water Treatment, Purification). Increases water output speed. |
Endurance (E) | Vault Door defenders & exploring. Increases health points gained per level (higher Endurance = more dweller HP). Also used in Nuka-Cola bottler rooms. |
Charisma (C) | Living Quarters breeding & Radio Studio recruiting. Speeds up dweller reproduction and improves chances of attracting new dwellers via radio. |
Intelligence (I) | Medbay and Science Lab. Increases production speed of Stimpaks and RadAways (medical supply creation). |
Agility (A) | Food production rooms (Diner, Garden). Increases food output speed. Also affects attack speed in quest combat. |
Luck (L) | All rooms (for resource caps bonus) & Wasteland exploration. Increases caps bonus on successful production and raises success chance when rushing rooms. Also helps dwellers find more caps and loot while exploring. |
Focus on training these stats to match each dweller’s job. A good strategy is to build training rooms (Weight Room, Armory, etc.) as soon as you can, and continually train your dwellers’ SPECIAL. Maxed-out stats make a huge difference in production speed and Vault resilience.
For instance, a dweller with 10+ Luck significantly boosts your cap income and rush success rate, and high Endurance on explorers means they survive longer and gain more HP each level. In short, SPECIAL stats directly affect room efficiency and dweller performance, so never ignore them.
Build a dedicated Fallout Shelter Guide for yourself by noting which stat each room needs, and train your people accordingly.
Fallout Shelter Tips for Success
Even once you have the basics down, managing a Vault can be challenging. As a seasoned Overseer, here are some pro tips and tricks to keep your Vault thriving:
Train Constantly
Never let your training rooms sit empty. Continuously improve your dwellers’ SPECIAL stats. Max level 10 SPECIAL dwellers work twice as effectively. This also prepares them for tougher challenges later.
Explore the Wasteland
Regularly send dwellers out to explore. Give them your best weapons and a good supply of Stimpaks/RadAways. Exploring is the best source of caps, weapons, outfits, and junk. Leveling up dwellers and finding loot outside will hugely boost your Vault’s progress. (Tip: Recall explorers before their health gets too low, or have enough caps to revive them if they perish.)
Keep Dwellers Happy
Happy dwellers work harder. Aim for 90%+ happiness by keeping resources plentiful and assigning dwellers to their ideal jobs. If a dweller’s happiness drops, check if they need a change of job or if resources are low. Breeding dwellers (or using the Radio room) can temporarily boost happiness as well. High overall happiness gives a production bonus.
Utilize Mr. Handy
If you earn or purchase a Mr. Handy robot, put it to work. Mr. Handy will automatically collect resources on a floor and can help defend against incidents. He has decent health and will revive (for caps) if destroyed. While not essential, Mr. Handy can take some micromanagement load off you and provide a safety net during attacks.
Manage Incidents Wisely
When a random incident (fire, radroach, mole rat, etc.) breaks out, assess if your dwellers can handle it. If not, evacuate them from that room – an empty room’s disaster will eventually clear on its own without spreading. This tactic is especially useful if you adopted the checkerboard layout discussed earlier. Save your dwellers’ lives by knowing when to fight and when to flee.
Plan for Endgame Threats
As mentioned, Deathclaw attacks start once you have 60+ dwellers. Make sure by that time you have a solid arsenal of weapons (laser rifles, plasma guns, etc.) and some high-level guards. You can also build healing rooms (Medbay/Science Lab) early and stockpile Stimpaks for healing during attacks. Each Deathclaw attack will typically hit 3 rooms, so have backup defenders on the second floor as well. With good preparation, you can repel Deathclaws and even legendary boss attackers later on.
By following these tips, you’ll prevent common mistakes and keep your Vault running like a well-oiled machine. Many Overseers lose their Vaults due to neglecting one of these aspects – now you won’t be one of them!

How to Get More Dwellers in Fallout Shelter
Expanding your Vault’s population is important, but you must do it wisely. Here’s how to get more dwellers in Fallout Shelter (and some advice on managing growth):
Breeding in Living Quarters
The primary way to get new dwellers is by breeding. Drag a male and female dweller into a Living Quarters room. Their relationship will progress and eventually the female will become pregnant. After a few hours, a baby is born. Babies take time to grow up (another few hours) and will start at level 1. Vault-born dwellers can become your strongest assets in the long run, since you can train them from level 1 to have max stats and high health. Just be careful not to breed too many at once – each baby is a new mouth to feed!
The Radio Room
Build a Radio Studio to attract wasteland survivors. When manned by high-Charisma dwellers, the radio can periodically bring in a new dweller from the wastes. However, there are drawbacks: dwellers recruited via radio tend to arrive at higher level (so they have fewer level-ups to gain extra health, making them slightly less powerful long-term than a vault-born dweller). Also, using the radio increases the chance of Raider attacks on your Vault. So use the Radio room cautiously – it’s a convenient way to get more people, but comes with risk.
Lunchboxes and Quest Rewards
You’ll occasionally earn Lunchboxes (card packs) through objectives or events. Lunchboxes often contain dwellers – sometimes even rare or legendary ones. These legendary dwellers come with high starting stats and great gear, giving your Vault a big boost. Quest lines in the game can also award special dwellers upon completion. While you can’t grind these reliably, always take advantage of a free dweller from a lunchbox or quest when you get one!
Vault Capacity
Build enough Living Quarters to increase your population cap. Each Living Quarters (especially when upgraded or merged) raises the number of dwellers your Vault can hold. You can have up to 200 dwellers max. There’s no rush to hit that cap – in fact, growing too fast can trigger tougher enemies and strain your resources. Expand in step with your ability to feed and power everyone.
Pro Tip: Do not increase your population beyond what your resources can support. The purpose of this Fallout Shelter guide is to give you the best start, so if your food and water are consistently in the green and you have surplus, then it’s safe to add a few more dwellers. But if resources are tight, hold off on breeding or recruiting. An overpopulated Vault with hungry, thirsty people will quickly spiral into chaos. It’s better to have 50 well-fed, happy dwellers than 100 miserable ones. Expand gradually, train the new folks, and repeat. That’s how to get more dwellers in Fallout Shelter without wrecking your Vault’s stability.
Fallout Shelter Trophy Guide (Achievements)
If you’re an achievement hunter, Fallout Shelter has plenty of goals for you. The game features 35 achievements/trophies in total (on platforms like Steam, PlayStation, Xbox, etc.). None are technically missable, but reaching 100% completion will take time and planning. Some trophies will naturally unlock as your Vault grows, while others require focused effort. Here’s what to expect:
Progression Milestones
Several trophies are tied to Vault growth. For example, you’ll get achievements for reaching 50, 100, and 200 dwellers. Another, “Vault-Tec Architect,” unlocks after building 25 rooms. These will come with steady play as you expand.
Resource and Production Goals
You’ll earn trophies for accumulating resources or items. Armed and Dangerous requires collecting 20 legendary weapons, and Fashion Statement requires 20 legendary outfits. This sounds daunting, but remember you can craft legendary items or find them on quests. Likewise, there are achievements for collecting a certain amount of caps, Stimpaks, etc., which you get through normal play or a bit of grinding.

Quest and Combat Achievements
The game includes quest-based trophies, like completing 30, 60, and 100 quests (the Urban Ranger, Survivalist, and Legend of the Wastes achievements). Quests are the missions you run after building the Overseer’s Office. Progress through quests regularly and you’ll hit these targets. Combat-related achievements include defeating raider bosses or legendary creatures during quests. Make sure to send well-armed teams on quests to tackle bosses for those trophies.
Dwellers and Stats
Some achievements involve your dwellers’ development. You’ll get one for leveling a dweller to 50, and another for raising a dweller’s SPECIAL stat to 10 (max) through training. Focus on a few dwellers to max out and you’ll unlock these naturally. There’s also a trophy (Hard Work is Happy Work) for having 50 dwellers at 100% happiness – keep your people pleased and this will pop up.
Time and Patience
Overall, expect the platinum or 1000G (for Xbox) to take dozens of hours. Estimates range around 80-100 hours of gameplay to unlock everything (depending on luck with Lunchboxes and how actively you play). The good news is Fallout Shelter achievements are mostly a fun extension of the gameplay – you’ll be building a thriving Vault in the process of earning them. Just be prepared for a bit of a grind, especially for those legendary collectibles and quest completions.
One more tip for trophy hunters
If you are desperate, some players resort to using the time skip glitch (changing device time) or modding their save to speed up progress. Use caution – messing with your device time can break your game, and using mods or save editors might void the satisfaction of legit completion. It’s absolutely doable to 100% Fallout Shelter through normal play, so take your time and enjoy the journey to that final trophy.

Fallout Shelter Online – What Is It?
You may have heard of Fallout Shelter Online, a separate game related to Fallout Shelter. Here’s the deal: Fallout Shelter Online is an official sequel/spin-off with added online features and multiplayer content. It expands on the original base-building formula by introducing PvP elements, guilds, and collectible heroes. You still build and manage a Vault, but you can also battle other players’ squads and take part in online events.
As exciting as that sounds, there’s a catch – as of now, Fallout Shelter Online is only available in certain Asian countries. It was released in regions like China and Southeast Asia, but not in North America or Europe yet (as of 2025). There’s no official global release at the time of writing. You can technically download it via APK or other workarounds, but the game is in a different language and requires regional servers.
For the majority of players worldwide, the focus remains on the original Fallout Shelter (single-player). If Fallout Shelter Online does come to your region in the future, it could be worth a try if you want a more competitive or social experience. But if you prefer the relaxed, offline nature of the original, don’t worry – Fallout Shelter itself is a timeless experience. This Fallout Shelter guide concentrates on the classic game that everyone can play.
So unless you’re in the supported regions or eager to jump through hoops, you can safely treat Fallout Shelter Online as a fun piece of trivia and keep enjoying your Vault in the standard game.
Fallout Shelter Save Editor – Cheating Your Vault (Use at Your Own Risk)
Running a Vault can be tough. If you’ve ever thought, “I wish I could just magically give myself unlimited caps or max out my dwellers,” well, some clever fans have created tools to do exactly that. The Fallout Shelter Save Editor is a fan-made tool (available on PC and Android) that allows you to modify your Vault’s save file. With a save editor, you can literally edit your Vault to your liking: add resources, change dwellers’ SPECIAL stats, give yourself rare items, you name it.
For example, the save editor by Rakion99 lets you grant max stats to all dwellers, fill your storage with caps, lunchboxes, and even remove rocks from your Vault with a click.
Sounds amazing, right? Before you download that cheat tool, consider the downsides. Using a save editor will take away the challenge and fun of the game. A huge part of Fallout Shelter is gradually improving your Vault and earning your rewards. If you suddenly grant yourself 999,999 caps and every dweller is perfect, there’s not much game left to play. Also, tampering with the save could cause glitches or crashes, especially if the editor isn’t updated for the latest game version. And if you care about achievements or trophies, using a save editor might disqualify you from earning them legitimately.
That said, it’s your game – if you want to experiment or recover a lost/corrupted Vault, the save editor is out there as a tool. Some Overseers use it after they’ve beaten the game to create “sandbox” Vaults or to test layouts without the grind. If you do use it, make a backup of your original save (so you can revert if something breaks).
Remember that the save editor is unofficial, so use it at your own risk. Since you have read this Fallout Shelter guide, it is not that difficult. For most players, I recommend enjoying the game as intended. But it is good to know this option exists in case you ever need to fix a problem or satisfy your curiosity.
Conclusion
Managing a Vault in Fallout Shelter is a balancing act of strategy, patience, and a little luck. But now you have the knowledge of a seasoned Overseer. With this Fallout Shelter Guide on vault building, resource management, dwellers, and more, you’re well-equipped to build the best Vault possible.
Keep your people happy, train them diligently, and protect them from the dangers of the Wasteland. Soon you’ll have a thriving, efficient Vault that even Vault-Tec would be proud of. Good luck, Overseer – your dwellers are counting on you!
Enjoy the wasteland adventure and happy vault-building!
