You can also check and learn something more about him otherwise there's probably some videos on YouTube. But if you want to know exactly what happens here's a little something. I'm not even going to try to explain what happens if you talk to Father because it's extremely spoiler heavy. if i never get closure then i want to not kill father b4 he speaks so i can probably get the full story and interactions with shaun.tho idk how the game is yet. i figure if i let father talk, etc my character and I would know probably. do u think my character will ever find out what happened or was the deal with him. :so since i killed father b4 he spoke.shaun never spoke again. so i wont get main RR quests or something? cause i tried to take them the holotape, but dez didnt take it. So now i cant do the railroad way? only minutemen or BOS cause i didnt hear father out? i still got a quest from P.A.M. Killing him only prevents you from completing the game with the Institute and Railroad, you'll still have the options with Minutemen or Brotherhood. You don't need Father alive to attack the Institute.

To be honest I may try that on a second play through and see what happens. But I could be wrong since killing him like that is an option. I haven't completed the main story yet but I assume that with Father dead you won't be able to complete the main story. When I went back to Sanctuary, where I built mine, it was destroyed and can't be used and can't be rebuilt. But I am pretty sure that the teleporter is a 'one and done' item.

Originally posted by Jeff Kaos:I did the same thing (shot Father and the whole Institute goes nuts) but I reloaded the game after fighting my way out so I can't help you there.
