I had three six people rooms fully armed, level 20+ wiped out by molerats. Despite my 30 stimpaks and constant healing. Then half of my vault was wiped out after that by a massive rush of them. I survived only because they left.


This game is broken




Wouldn't surprise me if the game was made to increase difficulty the longer you go without purchasing lunchboxes.

If it was level 3 rooms, that is why. You aren't meant to upgrade rooms till you're high enough level and have good weapons. Every time you upgrade a room, the rad roaches and mole rats that spawn there increase in number and power.

That's idiotic, it should be based on population not room level.

I lost my first vault to this same issue. I know exactly how you feel. I'm still nervous upgrading any room as I don't know how it's been balanced. Should they be level 20 for level 2? 25? What kind of weapon damage do they need? There's no guidance in the game, it's all trial and error where error could lead to death.

I hear you, the game should have an online manual of some kind. That said there's a lot of online player made guides. Those have been a huge help.


If I'd known about the upgrade/spawn increase I would never have upgraded EVERY room to max before moving on to the next level.


Going to have to restart.

At least you didn't spend any money yet. Some people did and had to resort to drastic measures to fix the problem.
