There's supposed to be a vault somewhere out here... a place called Vault 95. I've heard that Vault-Tec used it for some kinda social experiment... stuck a bunch of junkies inside to poke and prod. Well, they supposedly had some special method to clean up those blokes in there... some kind of a machine or somethin'. If we could get inside, maybe that machine could help me.Cait

10 Bring Cait to Vault 95Cait has confided in me that her dependence on Psycho is taking its toll on her health. I need to bring her to Vault 95 to cure her addiction before it's too late.
20 Locate the Clean RoomI've arrived at Vault 95 with Cait. I'm hoping the facility contains whatever it is we need to cure her addiction to Psycho.
70 Speak to Cait
80 Wait for Cait to get in the Clean Room Chair
90 Cure Cait's AddictionInside Vault 95, Cait and I have located the "Clean Room," an area dedicated to drug rehabilitation. After a short discussion, Cait has agreed to allow the Psycho to be purged from her body.

  • 在完成此任務之前,凱特會支持使用藥物的行為(e.g. when giving chems to Mama Murphy),但任務結束之後會轉而不喜歡這些行為。Even as she notes her resentment of her addiction in the dialogue that triggers this quest, her stance on chem use will not change until the toxin purge is carried out and the quest is completed.
  • The big guns bobblehead is off to the right after the initial firefight location. It is at the far end of the residential section of the vault, in the northernmost room.
  • 完成此任務才能解鎖凱特的最大好感度上限,也才能拿到她的個人特技。
  • 凱特不一定要一直保持在同伴狀態才能解本任務,在帶凱特到95號避難所目標完成後,接下來的流程即使凱特不在身邊,當抵達戒毒室時她會自動走過來,但如果她被分配到遙遠的聚落就要等很久。


  • Has platform::PCPC Has platform::Playstation 4Playstation 4 Has platform::Xbox OneXbox One The quest might not trigger after Cait's dialogue. If that happens, one can workaround this by not allowing her to talk about it (choose the "Maybe Later" option). At this point, she will need to leave the player character's party but can't be dismissed directly without triggering the dialogue. Find another companion and ask them to join. Send Cait on her way, and as she is leaving, talk to her. This will trigger the dialogue again and this time, the quest will show up in the quest log. [已验证]
    • Has platform::PCPC To trigger Cait's quest after the bugged conversation, one can also:
      1. Get rid of any companion (do this by talking to them and choosing the appropriate dialogue branch),
      2. Stand in front of Cait,
      3. Open console and execute setstage 1666c5 0.
      4. The player character will be teleported to a location near Vault 95 and "Benign Intervention" quest will immediately be triggered to start, so one can see it in their quest log.
      5. Talk to Cait and add her to the player character's party,
      6. From this point you can be sure that if you follow all other advises in this section you will not encounter any bugs during the "Benign Intervention" quest.
  • Has platform::PCPC To complete the "Find the Clean Room" objective, one will need to physically pass through the door leading to the Gunner commander. One may need to walk out and then back in if using V.A.T.S. or a perk like Blitz to enter the room rather than by walking through the door.[已验证]
  • Has platform::PCPC Has platform::Playstation 4Playstation 4 The elevator tends to get stuck upon entering it and activating the button. To fix this, simply restart the game.[已验证]
  • Has platform::PCPC Has platform::Xbox OneXbox One If Cait is wearing power armor when opening the door and entering the waiting room outside the Clean Room, it will disappear and not be recoverable after the procedure is finished. Have her get out of the suit outside of that area before proceeding.[已验证]
  • Has platform::PCPC If starting the quest while already in Vault 95 via normal means, it will become bugged to where returning to the entrance does not go beyond the first stage.[已验证]
