    To get this achievement, you'll need to side with the Brotherhood of Steel and complete all their quests.

    When you do The Molecular Level quest, you'll want to take schematics to the Brotherhood. Build the Signal Interceptor and Elder Maxson will give you a mission to get Doctor Li to join the Brotherhood again, do this quest (if you fail to recruit Doctor Li you will end up getting a different quest, recruiting Doctor Scara thanks to Wyyvern) and complete Institutionalized. You'll go back to Commonwealth to Elder Maxson, he'll give you the quest Liberty Reprimed. After this quest he'll give you Blind Betrayal, complete this to get the quest Tactical Thinking. (You'll get to kill the Railroad)

    Once you get rid of the Railroad return to the Brotherhood and you'll receive Spoils of War this is the point of the game where the Institute will become hostile. Once you complete this quest you'll start the final mission called Ad Victoriam.

    If you're going to vote negatively, tell me why.

    I actually do not know, I assume you do because she has to do with the later quests. Try to continue with the brotherhood and let me know please.

    WyyvernSorry I took a while, but I can confirm you don't need to side with The Institute and get Li back to get to this quest and achievement. Maxson gets mad at you for about 20 seconds then gives you Liberty Reprimed anyway. You're tasked to recruit a "Professor Scara" who I assume takes Li's place.

    This is the last achievement in the Brotherhood questline (excluding The Nuclear Option, which can also be achieved siding with the Minutemen or the Railroad).

    While the solution by HardcoreBabyGrl shows perfectly how to get this achievement, I wanted to share a chart I made with the way of getting all the story achievements with only one save / reload, and also the best point to save in order to obtain all 4 endings (not necessary for achievements).

    Scroll down for a more detailed explanation (inside the Spoiler Tag, as it is an awful lot of text).

    For starters, keep in mind a thing: having high charisma will help you when you'll have to balance several factions at once. I recommend having at least 6-7 points of charisma, and using "charisma-enhancer" gear like Glasses, Hats or Suits, or even using, when neccessary, beer or some drugs as Grape Mentats or Day Tripper that give charisma points for a few minutes.

    Open this thing for the full explanation:

    Rafe HarwoodJust remember to do all of the Nuka World line before finishing When Freedom Calls if you want to keep Preston as a companion.
