so get a laser pistol from concord then head to diamond city, and find the area where you can buy a house. there is only 1 guard at night and do it when the front desk person isnt there. from here, you need about 21 bullets in his head or chest area to kill him, because he is really powerful and you have to do it fast. from there take his armor. through the hallway there is a chair that you can sit in (couches dont work) and wait 24 hours. now you have good early game armor and non hostile guards!!!
