There are a lot of companions in Fallout 4. Not only do they come with different weaponry/actions but they also come with their own unique perk. Read on for a list of all the companions and the locations you can find them. Fallout has only just been released so this list is not complete yet. I will add new companions as I discover them.
Can Companions Die?
Companions cannot die. At all. If a companion is wounded during a fight they will lie/sit down (you can give them a stimpack) and not help you for the duration of the fight. Once you are out of combat, they will stand up and continue.
