All Companions In Fallout 4 Locations And Special Perks

Exploring the post-apocalyptic Commonwealth in Fallout 4 can be a daunting experience when traveling alone. Recruiting allies not only provides extra firepower during combat encounters but also unlocks unique permanent passive abilities that significantly boost your character's build.
Early Game Followers and Initial Encounters
Your journey begins in Sanctuary Hills, where your faithful Mister Handy butler Codsworth resides and offers the Robot Sympathy perk upon reaching maximum affinity. Shortly after venturing out, players can meet Piper Wright in Diamond City, who grants the Gift of Gab perk that doubles experience gained from discovering locations and winning dialogue checks.
Another early ally is Preston Garvey, who is encountered at the Museum of Freedom in Concord. Mastering his relationship yields the United We Stand perk, increasing your overall damage resistance whenever you face three or more hostiles simultaneously.
Key Faction Allies and Tactical Benefits
Joining various factions across the wasteland introduces specialized companions with distinct skills. Paladin Danse located at the Cambridge Police Station grants Know Your Enemy, boosting damage output against Ghouls, Super Mutants, and Synths.
For players focused on stealth playstyles, Deacon can be recruited through the Railroad faction at the Old North Church. His unique perk, Cloak and Dagger, enhances sneak attack damage while extending the duration of Stealth Boys.
Town Mercenaries and Specialized Survivors
Goodneighbor serves as a hub for multiple recruits including Robert MacCready inside The Third Rail tavern. His Killshot perk dramatically improves V.A.T.S. headshot accuracy during combat encounters.
In the same settlement, John Hancock can be recruited after completing local quests to unlock the Isodoped perk. Meanwhile, players searching for terminal support can rescue Nick Valentine in Vault 114 to earn the Close to Metal ability.
Vault Dwellers and Combat Arena Warriors
Exploring Vault 81 allows players to meet Curie, a modified Miss Nanny who unlocks the Combat Medic perk to heal players at low health. For aggressive fighters, Cait can be rescued from the Combat Zone in Boston, granting Trigger Rush to speed up Action Point recovery when damaged.
Super Mutant companion Strong resides at Trinity Tower and provides the Berserk perk for enhanced melee combat. Once unlocked, all companion perks remain active permanently on your character regardless of who travels with you.
