One of my Vaults has a Fat Man. Another has a Guided Missile Launcher. I have equipped them on Dwellers in a 3-room "Deathclaw Death Pit". Even though both have been involved in multiple Deathclaw attacks, neither has ever been fired. The Dweller spends the entire attack running to the opposite end of the room from the Deathclaws. But by the time he gets to the other side of the room, the Deathclaws have moved such that the Dweller decides to run to the opposite side of the room.
So my question is, are the Fat Man and Guided Missile Launcher "for outdoor use only", or do I need to set up in a different sized room?
And is it true that SPECIAL stats don't affect weapon effectiveness?
Thanks.....
