Fallout 4 is a massive game from Bethesda that sees the Sole Survivor, the only person from their Vault to survive, emerging from Vault 111 in search of their son, Shaun, who was stolen from them during the time that the Vault Dwellers were in cryogenics.

Once the Sole Survivor starts their mission, they will run into countless companions who are willing to help them out. With some of those companions, the player can unlock special companion Perks. Here is a guide to those Perks and how to unlock them.

How To Unlock Companion Perks

In order to unlock these Perks, players will need to max out their affinities with their companions. Considering not all companions have Perks, it is recommended that players focus on increasing their affinity with those characters that do have Perks before focusing on others. Remember, even if the companion isn't traveling with the player, they will still benefit from their Perk, meaning that unlocking them is important. Here is how to increase affinities:

  1. Perform actions that the companion likes (this includes certain dialogue options and quest options)
  2. Stay away from what the companion dislikes (this can include things such as stealing, hacking, and lockpicking)
  3. Complete their personal quests (not all companions have them)
  4. Considering pursuing a romantic relationship with them
