Minutemen faction quest: Defend the CastleĪll three other factions will attack in waves. You may warn BoS instead if your plan is to work with Institute.

The game will warn you during this quest where proceeding with it means becoming enemy of Brotherhood so don't proceed. Do not go warn her and do not start Precipice of War because at that point BoS will attack Railroad and you have to defend them.

It's actually the last point of the quest Underground Undercover where you need to warn Desdemona. When you receive this one, don't proceed as it's siding with Brotherhood against Railroad. BoS will still be present in that fight so don't bother warning them too. During Battle of Bunker Hill, warn Railroad, kill courser you meet before he reaches Bunker Hill then lie to Father you got ambushed. If you're already past this point, it's still okay, all you need to do is to brin the tape Network Surveillance to Tinker Tom in Railroad after you used it in Institute (you may steal it from whomever you gave it to if you did).Ģ. During Molecular Level main quest, get Railroad's help. You don't choose one faction over other three but rather choose which one you'll dispose of first, then which one second.įirst you need to know how to remain "neutral" as long as possible.ġ.
