Fallout 4 Companions Guide: The Complete List

Fallout 4 is here and with it come new companions, one of the game’s most talked-about features. After you unlock each companion, they’ll follow you and help you fight; the catch is that you can only have one out at a time and each one has different perks, so you’ll have to strategize as the perks disappear once the companion is gone. In battle, they can get knocked unconscious but they don’t die. You won’t get XP if a companion kills an enemy unless you do damage to the enemy as well.

You can dismiss them, in which case they’ll go to your settlement or return to the place where you found them. But when they’re active, the distance between you doesn’t matter; the perk will always stay active too. (Basically, the rules of Pokémon apply here.)

Your goal is to build relationships with these companions by issuing commands to them and influencing them with your actions. Some things you do will be adored by some companions and hated by others. So, just like real life. Any actions performed in a settlement that stores multiple companions will affect all of them.

The interesting thing about companions is that you can build romantic relationships with a handful of them (Cait, Curie, Danse, Hancock, MacCready, Piper, and Preston Garvey — all humans or ghouls). In order to do so, you have to raise your Relationship level with that companion; if you reach maximum Relationship level with a companion, you can unlock the Loveable achievement.
