Other interactionsEdit

  • The Lone Wanderer encounters the leader and his squad when inside the mobile base crawler.
  • Because he is part of the Enclave, he will be hostile to the Lone Wanderer at all times.
  • He can be mezzed and enslaved. Removing the slave collar after putting it on him will make him friendly towards the Lone Wanderer.



  • He has no unique dialogue of his own, instead having the same voice pack used for generic Enclave Hellfire troopers.


Enclave Sigma Leader appears only in the Fallout 3 add-on Broken Steel.
