Fallout 4

I just started playing Fallout 4 (about 30hrs in right now). I'm really enjoying the game overall. I think I tried to go too fast with the main story line and now I'm stuck trying to kill the forge guys. My weapons just don't do enough damage to kill the 3 of the guys in there. I've started focusing on the missions for the Brotherhood of Steel so I can level up and maybe have a chance.
