How to unlock the Project Purity achievement in Fallout Shelter - Definitive Guide

Easy to unlock, you'll need to place 3 water type areas together and they'll merge into a single water room entity.

The best option is right from the start to put three water treatment rooms at 175 Credits each together in a row costing a total of 525 Credits to achieve.

Just a note for people who come here looking (probably, its broken for you too):

This achievement definitely suffers from breaking. If it doesnt trigger once a 3 merged room is created, it will never trigger on that save file. Start a new vault in an empty slot and do as above.

For this achievement you need to stick 3 water treatment rooms in a row. The water rooms cost 175 each so it will cost you 525 caps in total. You can ether make the rooms when you first spawn into your shelter ( WARNING this will ruin your game and you will have to restart) or you can wait till about 10-15 mins into the game and you will have enough caps by just playing the game normally.

If you would like a video guide for this though I will leave mine below

Start up a new Vault and use the funds to purchase three level one Water Treatment Plants and place them in a row.

Easy Trophy. You just have to build 3 Water Rooms, each costing 175 Caps, next to each other. The rooms will automatically merge.

You can merge rooms by building the same type next to each other, to build a bigger room. The rooms have to be on the same level, which means if you have upgraded a small room and you build a room next to it so you will need to upgrade it too or it won't merge. Merged rooms are very useful, because you will be able to assign more Dwellers to work on them and they will produce more resources, you should aim to merge every rooms that you can.

This achievement can easily be obtained by building 3 unupgraded Water Treatment rooms next to each other so that they merge together to form 1 giant version. When you do so, this achievement shall be yours.

Rooms are combined only if they have the same upgrade level, for example, if you built one water production room, then upgraded it to the second or third level, and then built another one next to it, they will not merge until the second room is upgraded to the same level as and the first one.
