Other interactions

  • 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.
