Brotherhood Of Steel is one of the factions in the game which players can align themselves with if they want. However, the more Brotherhood of Steel activities you take part in, the more your relationship with other factions will be negatively impacted. The following are the Brotherhood of Steel side quests that players will encounter in Fallout 4.
