Fallout Shelter (Patreon)

So even though I am obsessed over the puppy, she is not here yet and I do not intend to forget my gaming! To get me through my flight I played this game the whole time. The flight flew by. What's even funnier is that my vault is so much more advanced than depicted in this picture. The only thing I am having trouble figuring out is how to get my survivors vault to be just as advanced as this one. I can't seem to get very far on it. Everyone keeps dying and then there is no reviving them so I just don't have anyone anymore.

Do you have any tips?
