    This will come naturally when you play. If you want to get it done quickly, you can build a cheap room then destroy it, then rebuild it. Repeat the above steps. The room you destroyed will all count toward to this.

    It must be done under the same vault (savefile).

    And make sure it's the only room on your screen, because when you build the second room, the price will increase. For example the first power generator is $100, and the second will be $125, the third will be $150, and so on. If you keep destroying it, it will always be the first room and not cost you more money.

    NuttySandman123So if first cost 100 caps how much do you get back for destroying it?

    the Si1ver KingFor anyone still looking, for a contest or something, the answer is 20. You'll have to complete objectives and open lunchboxes for more caps if you want to brute force this on a new save. It took me about an hour and a half.

    This achievement is obtainable through natural progression. So of course you could always just build the rooms you need. However, if you would like to grind it out quickly I recommend building extra power rooms because the only resource they use is caps, they are very cheap, and they add to your total power storage. Any other room will waste power when built.
