Interactions with the player character

Interactions overview

FO76 ui icon quest.png
This character is involved in quests.


  • Trouble on the Homefront: If Mack has become overseer, it is impossible to reason with him. This eliminates one of the possible solutions to the quest.

Effects of player's actions

  • If the Lone Wanderer killed Alphonse during Escape!, Allen will be elected the new overseer and will be even more oppressive than the previous one.
  • In the event that he becomes overseer, Allen Mack cannot be reasoned with. The Lone Wanderer has to either kill him or help him to keep Vault 101 closed.

Other interactions

  • During the quest Escape!, Allen Mack can be seen in an inaccessible common room, pounding on and shouting through the glass to alert others to the Lone Wanderer's presence.


* Only during Trouble on the Homefront if he becomes the overseer.


  • During the quest Escape!, it is impossible to enter the room where the Macks live (without console commands). Viewing Vault 101 in the G.E.C.K. reveals that Mack's "room" is just a short stretch of the corridor without an entrance. It is impossible to enter his room due to the fact that he is scripted to become the new overseer should the current one die.
  • One of his combat lines include "The Overseer will hear about this!", even after he becomes the overseer.
  • Even if Mack becomes the overseer, Amata will still refer to the overseer as her father.
