    LuckyDay21Yep this was super bugged on Xbox X (2023). I ended reloaded a super old file. I tried all the basic reload old game, reboot game, reboot xbox. force close and try. Nothing worked.

    FInally gave in and loaded a very old save file, The only thing I did this time was super rush the story and set off the Rocket Engine. I think I forgot to do that the first time. Might be needed to do all optional items as well. Otherwise, I don't know why else this time it worked.

    fucking buggy ass game.

    SharableTexas1I kept getting the bug too, but tried “unsure” as my response and then joined later. Totally worked.

    Glowblue1If you kill all the ferals around the Cambridge police station and Danse just keeps saying “Check your fire, we’ve got hostiles!” over and over, here’s how to fix that:
    - Play the main questline up to The Molecular Level. Bring the item you obtained at the end of the previous quest Hunter/Hunted to Tinker Tom and you’ll be sent back to the super mutant who wanted the data from it.
    - The super mutant will recommend that you get help from your friends. You’ll get three optional quest objectives, one of which leads you back to Danse. Go back there, he’ll talk to you now.
    - DON’T accept his offer to join the Brotherhood right away or he will bug out again after the conversation. Refuse, then talk to the other BoS members. Now you can go back and accept, Danse will tell you to go in the police station, and the Fire Support quest will finally complete.
    - Talk to Danse to start the next quest, Call to Arms, to get the deep range transmitter and follow Danse. When he enters ArcTek he will probably say one line then turn around and immediately leave. This bug tends to happen if you got the previous bug.
    - If you follow Danse he will go to Greygarden or back to the police station. Ignore him and work your way through ArcTek. You won’t get the flavor text or guidance from him but you don’t need him to be there to complete any of the quest objectives, even the one for following him.
    - When you get the range extender, he’ll appear with you outside and offer you BoS membership. Whether or not you accept now, he’ll then say to meet him at the police station. Fast travel back there, he’ll be inside.
    - Go inside. Call to Arms will complete and Semper Invicta will start. Agree to membership, the quest will complete and you’ll get the achievement.

    GD it Bethesda, fix your s***

    This can be done at almost any level. I was level 4 when I found the radio transmission. Completing the quest to the Police Station actually gave me a whole level and I received
    Fallout 4Born SurvivorThe Born Survivor achievement in Fallout 4 worth 5 pointsReach Level 5

    Once I completed the quest I was half way through level 6. Danse is a beast and will actually tank and kill everything for you.

    I just followed this guide and worked out fine. https://www.vg247.com/2015/11/07/fallout-4-how-to-join-the-b...
