every achievement completion guide

you should get every achievement in this section naturally as you will have to play naturally for quite a while building up a maximum capacity vault in all likelihood. I will go over each one just in case there are issues.

"Atom Splitter", "Dine and Dash", and "project Purity" are for building and merging 3 of each of the main necessity rooms being power, water and food. you will likely get these 3 achievements within your first or second play session since to have all your dwellers working and to support the vaults initial capacity and influx of dwellers in the first hour you will need to do this

"mattress Stuffer" and "A Vault For My Vault" are for collecting 1000 and 10000 caps you will get these naturally if you stick with the slog. you earn caps from lunchboxes, daily log ins, tasks, leveling dwellers, completing quests, exploring the wasteland, finding the mysterious stranger, finding Cappy/Bottle, selling weapons, outfits and scrap, and raising special stats of dwellers.

"Home Sweet Home" is for building 1 of each room you will unlock room types as your population grows

"vault-Tec Architect" and "vault-Tec Engineer" are for building 25 and 50 rooms respectively. you will get each just by building the necessary rooms to maintain/ increase population, storage and resource gain

"A Better Future, Underground" is for upgrading 20 rooms to level 3 you will get this naturally while maintaining your vaults population as it gets bigger.

"Better Settler", "Higher and Higher" and "Overseer" are each for reaching level goals for dwellers having one at level 10, 25 and 50 my recommendation for leveling up dwellers in the late game is as you max each of their special stats equip them with a good weapon, 25 stimpak's and Radaway and send them into the wasteland for a few days they will either die in which case you can revive them and recall or they will automatically reach capacity and return on their own in both scenarios they should reach level 50 if they don't simply repeat this process.

"hard work is happy work" this achievement is for successfully rushing 50 rooms you can sit there and rush rooms over and over to reach this faster but later achievements make this relatively pointless since you will need to play a lot. this is a way to earn caps early but it can also get your dwellers killed before you have resources to revive them so i recommend only doing it a few times for each room each time you start a session.

"Prepare For The Future" make 25 babies for this as well as increasing your early population quickly i suggest you pick a male dweller with your highest charisma (if you are lucky in one of the initial lunch boxes/ starter kits if you buy it you will get a rare or legendary dweller to fill this role) and have them get with all your female dwellers if you have a charisma boosting outfit have the female wear it and swap it between if you have 2 have them both wear it. this will speed up the process you can have 2 or 3 male dwellers to speed it up a lot however in the early game this will massively hurt your resource gain since you may only have 13 or so dwellers so having 6 tied up at a time is not recommended.

"Overachieve Much?" for this you will have to sign in daily complete objectives and use your free skip to get rid of ones that take a long time or have terrible rewards if you want to avoid spending money on this game I recommend you at least try every objective with a lunchbox for a reward since this can save you a LOT of money or time for a very annoying achievement i will be saving for last. if you're lucky you can knock out a few in a row with little effort especially in the late game the worst are reliant on random events.

"you're fired!", "wasteland Wanderer", "Urban Ranger", "Survivalist", " legend of the Waste", "Enemy of the waste", "big Pharma" and "smooth Talker" are all reliant on doing quests you will have to complete 10, 30 and 100 quests. kill 500 enemies and 10 bosses on quests which will happen naturally on your way to doing 100 quests. collecting 100 stimpaks and radaway should also happen naturally while doing 100 quests. and you will need to do 25 dialogue options during quests which will also happen naturally on your way to 100. in the endgame when you have 200 dwellers i recommend you have 3 quest parties of level 50 dwellers with your best weapons and armor to bang out 3-6+ quests a day

"interior designer", "Paint'n elbow grease", "decorator", and technically "more than Handy" are all reliant on you getting room themes. you can only get these from dwellers in the wasteland and quests. you will need to find and craft every room theme i believe there are 8 room themes each is made of 9 fragments so there is a 1 in 8 chance of you getting a fragment of each theme because thankfully each fragment is only tied to the room and faction. unfortunately you can get fragments of themes you have already completed before you get the ones you need so this can take quite some time you will likely get 1-3 fragments for each quest and for having a dweller in the wasteland for like 4 days. this means it can take quite awhile to find all the fragments and craft each of the themes. all that considered there were still 2 achievements that took long enough to get i aquired all of these naturally.

"weapon smith" and "Fashionista" are for crafting 10 weapons and outfits you can get this fast by crafting worthless commons or you can spend literal real life months or dollars because this is after all a mobile game originally crafting legendry's it will take an hour or so to craft commons and multiple days for legendary's and this is with 6 dwellers with 10 in the relevant stats. otherwise its about 20 nuka colas for legendarys time skip which is about 1/5th of 40 dollars if i remember correctly... yea do not spend money on this because again you will likely get this naturally because there are worse achievements.

"a little off the top" just customize 10 dwellers in a barbershop this will take about 5-15 hours.

"armed and dangerous" and "Fashion statement" these are for collecting 20 legendary weapons and outfits you can acquire these from quests,crafting, and lunchboxes

"scraptastic" once you get to the late game start collecting all of your common weapons and armor and scrap them rather than just selling them this will take awhile but you will also receive around 100 commons and uncommons for every legendary item so it won't take too long compared to other achievements

"Get off my lawn" is an achievement for fending off 50 raider attacks and i had many problems with this achievement despite it sounding like one you would get naturally. for starters raiders are added to the random incident pool at about 19 dwellers which means that you are likely to get 1 raider attack in every 3 or 4 random incidents however as your population grows the pool increases at 70 dwellers which you will reach quickly after the first 30 or so you have the entire pool which means the random incident which occurs ever 15-30 minutes could be a fire, Radroaches, mole rats, Radscorpions, Deathclaws, ghouls, raiders, aliens, and possibly synths if they're still in the game. so the optimal strategy is to have a vault at about 23 dwellers you leave open for awhile. i managed to get about 32 raiders naturally while doing every other achievement because almost every other achievement can be farmed while you aren't actually playing and are waiting for timers to count down. this is the opposite where you have to have the game open and running to actively have the chance. this is annoying cause in a high level vault you likely won't get raiders and in a low level vault you don't have the power to have the vault sustain itself while you wait you have to manually collect resources and heal dwellers. I've heard you can force random encounters by sending dwellers to the wasteland but that's mostly a rumor I had limited luck with it. I've also heard that having a radio going increases your odds but this also likely leads to increasing your vaults population unless you leave the dwellers waiting outside.
IMPORTANT. this is the last achievement i got and while going for it i had a bug. i had a 200 dweller vault and a smaller vault specifically to farm raiders but at 42 raider attacks they stopped counting for the smaller vault so i switched to the larger vault assuming something made it so only it would count. there was nothing wrong with my cloud save and i validated my files with no issues found but once i did this and switched to the big vault every incident originating from outside suddenly counted toward the achievement meaning while i did have 8 or so incidents in the pool i still had about a 50% chance of it counting even still this took a long time and was exhausting.

this is among the worst achievements in any game I have ever played for one simple reason and that is that it was originally designed to force achievement hunters to spend money and still to this day is to an extent but after 10 years they finally made it more possible to do for free or at least cheaper. for this achievement you will need to collect 20 legendary dwellers. They all have to be in the same vault. unlike weapons and outfits these can't be crafted and are only obtained from 2 or 3 quests and lunchboxes. luckily with the first season thing you could get about 5 legendary dwellers and it seems you can still get a few each season but you still might need to spend money. to get this naturally is hell. you get 3 from quests and maybe a few you can transfer from the season but you still need a lot which can only be gotten from lunchboxes aka lootboxe's. I've found you will get about 1 legendary dweller in every 40 lunchboxes which if you spend money is about 1 in every 20 dollars 10 dollars if lootboxe's are on sale for holidays. this is unforgivable greed. to get lunchboxes naturally you can get 1 every week by signing on every day and maybe 2 more from objective rewards and quests. this will take you years to do naturally signing on every single day probably twice a day to always have all of your crews on quests and always clear the objectives. or you can buy lunchboxes or you can save a little and do a bit of both by doing the new season things which will require about 10 bucks on the season but gets you legendary dwellers the first season gave about 5 so if that's consistent you can get 20 from doing the season quests and buying the seasons but this will also take ages since you have to do the season in an experimental vault and your own since they ALL Have TO BE IN THE SAME VAULT so it will take you about 30-40$ and a year of seasons to do this semi naturally now.
