I did this just last night at Starlight Drive-In, and I can confirm that it works. Here is the text of the method (and the end of my actual contributions). It should occur like this:Ĩ0>84>88>91>93>95>97>98>99>99>100, I used a Level 3 (Restaurant) to get those numbers, but it can be done with level 2. It will be slow the first day, but then you'll notice progression. No super huge amount of settlers, no need of caps in excess of 30k. I'll post the full details, but here are some summary items.ġ x Settler (moved from other settlement)ġ x Sleeping Bag (or any bed, must be under cover) If this helps you, go there and give lunamoonraker some love, because this simplifies an arduous task. The author,, gave me permission to post this solution here.

Good luck guys, hope this helps some of you get this annoying achievement popped! i think people have said this already on other solutions but do not leave the settlement for any reason as your happiness will go down. Now all you need to do is wait, i personally did this without a companion, not sure if this makes a difference or not but anyway sleep 2-3 days, ring the bell, sit on the chair for 12 hours then go for a little wander about, keep repeating this until the achievement pops. Start off by building your beds, making sure they are all under cover, water pumps, mutfruit plants, clinics and heavy machinegun turrets wherever you want them round the gas station, put a couple of bar stools at the front of the shop, tv set in the corner and the odd picture here and there, i put a statue outside just for good measure, build a bell and chair near your clinics then go round the back of the building and build a load of wooden crates until the size meter turns from green to yellow, you can find wooden crates under furniture/containers, once you have set this up go to a larger settlement and send 6 settlers to the red rocket by clicking X on them to move them, once your 6 settlers arrive assign 5 of them a clinic each and the other one to the mutfruit plants. You will need 6 settlers, 7 beds ( one for you), 5 tier 3 clinics, 6 mutfruit plants, 3 water pumps, 10 heavy machinegun turrets, a bell, a chair, a load of wooden crates, and a few decorations just to be on the safe side. By far the best place to do this is the red rocket just outside sanctuary hills, you dont need to buy anywhere near as much stuff for the achievement than the other solutions posted here,
