The members are identifiable by their colorful outfits and bizarre face paints. Most members wear masks depicting an animal. The hierarchy of the Pack is similar to that of wolf packs, with the leader being known as the alpha. It is common for there to be challenges for the alpha title which ends with the dominant, and often most violent member, being victorious. As Pack law forbids killing other members, the losers are generally shamed and then exiled.
The Pack are one of the gangs the Sole Survivor can choose to help during the Nuka-World add-on. They can do odd jobs ranging from slavery to murdering informants of other factions, and help give them new territories around the park as well as giving them settlements in the Commonwealth. Depending on the ending for the raiders; they can either remain allies or end up being the final bosses with the Operators and the Disciples helping you eradicate them.
Alternatively, they and the two other raider groups can be destroyed in Open Season.
