We definitely wanted to present new challenges for players. If you're feeling underpowered, here's a couple things to try.
1) Open the vault door less. The more you open the door, the more susceptible you are to attacks.
2) Consider vacating some of your radio stations. The more foot traffic driven towards your Vault will lead to more attacks.
Thanks for sharing all the feedback. We continue to look at what players are saying.
All my vault is either dead of at 5% health and suffering radiation poisoning, meaning a trio of deathclaws or a molerat infestation will destroy everything.
They happen at random and I have no dwellers free to run the radio or go out exploring. So this theory does not work.
Whole vault is dead. Am just uninstalling. Good try Bethesba. Maybe will try again in a few months.
