The hierarchy of the Pack is based on wolf packs, with their leader being referred to as the "Alpha," they follow the rule of 'survival of the fittest'. As with certain other animals, (e.g. peacocks), they use their colorful and outlandish looks to boast.
It is common for Pack members to challenge the reigning Alpha to win the title, which ends with the winner remaining as the dominant of the pack, which usually means that the Alpha is the most violent member, but not the most capable leader. As Pack law forbids killing other members, the losers are generally shamed and then exiled.
The members are identifiable by their colorful outfits and bizarre face paints. Most members wear masks depicting other animals. The Pack feeds the carnivorous animals they keep with human remains. Evidence for this can be found in the Nuka-Town backstage.
The Pack is one of the gangs the Sole Survivor can choose to help during the Nuka-Worldadd-on. One can do odd jobs ranging from slavery, to murdering informants of other factions, to reclaiming supply caches in the Commonwealth.
As with the other Nuka-World raiders, the player character can give them new territories around the park as well as giving them settlements in the Commonwealth. Alternatively, they and the two other raider groups can be destroyed in Open Season.
In the quest Power Play, depending on the number of settlements and Nuka-World parks they have been given, the Pack can either remain allies alongside the Operators or Disciples, or will turn against the Sole Survivor.
Pack faction armor offers a fair amount of well-balanced protection akin to combat armor, but is about half again as heavy. Though slightly weaker than Disciples or Operators armor, their gear can still surpass heavy combat armor in terms of protective qualities. Since every single gang member is equipped with at least a few parts of their armor, it often means that even the most basic Pack fighter boasts better resistances than raiders or Gunners of much higher levels. This, coupled with their powerful weaponry, makes them a lot more dangerous than their Commonwealth counterparts regardless of player level.
The perk affiliated with this faction is Pack Alpha.
