Although Fallout 4 is a single player RPG, it doesn’t mean you have to be alone in your adventures! Once you set off to explore the Commonwealth, you will have the chance to recruit a variety of unique companions. They range from a lovable dog to a fearsome super mutant. These companions are more than just company on the road! Companions can be equipped with gear such as clothing and weapons.
They can carry some of your gear, and any junk you pick up as well, in addition to helping you in battle. In battle, companions cannot die. However, they can go down. The only way to get them up is to use a stimpack on them.
Additionally, each companion has an unlockable perk. The companion perk is unlocked through time as they journey with you. Companions (except for dogmeat) will react to your in-game actions and choices. Enough positive reactions will allow you to unlock their perk, a romance option, and their personal sidequest! Only one companion can be with you at a time, so choose carefully. There are thirteen companions in the base game, with an additional four companions if all DLC is purchased.
