i just now figured this out. one was blocking a doorway, and i was in no mood. i saved the game, figuring i was about to turn them all hostile, and popped him. he just said 'ahh!' and got knocked back. no hostility. i'm sure a lot of you already knew this.

It kind of varies. Sometimes you can go so far as to kill a settler without making the others hostile. Other times you can accidentally hit someone with the impact radius from landing in power armor and the whole settlement aggros.

Yep, that's what I do when they spawn on the roof or get stuck somewhere.

I do the same with the cows.

Just don't keep continually punching them til their health drops too far and they turn red, starting a revolt, or you will have to leave for a while.

Yeah, I even used to flip a settler away with bare hands just for the heck of it and she didn't even mad.

Even if you accidently turn them hostile. sheathing your weapon should turn them friendly again. Should being the keyword here.

Is there a way to switch quickly from your gun to fists without having to go into your pipboy?

Shoo-ryuken!

I punch Marcy every time she opens her mouth, for some reason it's very theraqeutic...

I haven't found a means to do so. It's annoying when trying to switch between my missile launcher and costs, that's for sure.

Well, theres one alternative to microwaving kittens.

Ha...that is funny. I think I'll try it. She is such a grumpy gus.
