Trust can be earned by assisting them in certain missions such as Trading, Supply Runs or Besieged. The higher the Trust level, the lower the Influence cost for taking items from their Supply Locker. Trust is the measurement of the Enclaves' attitude towards the player's community. None of the survivors in State of Decay are openly hostile towards the player's community however, some may express dislike or disdain towards them. All randomly generated Enclaves can be recruited, while the members of uniquely named Enclaves ('The Grange', 'The Wilkersons') are usually not recruitable. Many of the survivors are fixed and associated with storyline missions, while others are randomly selected and put in small communities (Enclaves with generic names like 'Friendly Survivors').
4.2.7 Other survivors tied to storyline missions.
