Can you get the Brotherhood of Steel to join yes man
The answer to this question is a resounding yes! In fact, the Brotherhood of Steel is one of the few factions in Fallout: New Vegas that can be recruited to join the player character’s side through the use of the Yes Man perk.
With the Yes Man perk, the player can convince the Brotherhood of Steel to abandon their base in the Mojave Wasteland and join them in their quest to take down the NCR. However, before the player can do this, they must first complete the quest “Still in the Dark.” This quest tasks the player with killing all the nightkin in the Dark Brotherhood Sanctuary. Once this is done, the player can then talk to Elder McNamara and convince him to leave the Mojave Wasteland.
Once the player has the Brotherhood of Steel on their side, they will be a powerful ally in the fight against the NCR. The Brotherhood of Steel is armed with some of the best technology in the game, and their troops are some of the most skilled fighters in Fallout: New Vegas. With the Brotherhood of Steel on your side, the NCR will have a much harder time taking control of the Mojave Wasteland.
