I was wondering if I could somehow pull off killing the Railroad, Institute AND the Brotherhood?

I blew up the institute just now, and thought I could go in and finish off the brother in some way. Destroy liberty prime and their ship. But have no idea how.. and am sadly thinking I won't be able to. :/

If there is any way, how would I do so?

i think it might be too late, you had to have done it BEFORE you destroyed the institute. You had to get the artillery set up in a certain amount of area's i think.

I can always reload a save, however can I still destroy the Institute together with the minutemen after destroying the BoS?

Because you have to work together with the Institute to be able to destroy them, right?

nope, once you get enough artillery/settlements/etc, you can apparently command the Minutemen to wipe you all other factions.

Oh? So they disable their airship, too? And what about Liberty prime? Who would I talk to anyway to do this?

SPOILERS [censored]

you supposedly talk to Preston, otherwise, not sure, your probably use all the artillery to blow the airship out of the sky.

Wouldn't I technically be able to kill both BoS and Institute together with the railroad, then betray them and kill them as well leaving me along with the minutemen?

nope, pretty sure you HAVE to tell preston you do not want to help any of them at all.

This is not a Tabletop RPG, where everything you think of is possible, the only things that are possible are what the devs thought up.

It is possible.

1. Give Sturges the Holotape from "Inside Job"

2. Kill the Railroad for the Institute

3. Betray the Institute

4. Destroy the Institute with the Minutemen

5. Destroy the Brotherhood with the Minutemen.

If you need any deeper explanation, just ask.

This

I was waiting for someone to point this out lol

By betray the institute do you mean just start helping the minutemen or something else?

start shooting everyone in the institure until it says "you are now hostile to the institute"

yep i think that step just means go against them and make them hostile.

its because if you just stick with the minutemen they wont attack the railroad (i think). So you want to use either the brotherhood or the institute to get rid of the railroad, then side with the minutemen and remove the other two.

Yep. The Minutemen aren't hostile to the Railroad so you have to go around it using another faction.

Alright, I pretty much did all of that. But do the Minutemen actually destroy their ship and Prime then? How do you get these quests? Be cause I've done every thing you explained up to point 4 you're remarked, so I've only got the BoS to deal with.

My second play through I've avoided any extra missions for Minutemen, I haven't even made contact with the BoS other than be attacked occasionally by their Vertibird patrols, they don't fair well with these because I get the Party Starter out.

I'm just making a direct line for the Institute and will be trying to stick with them only and hopefully they'll lead me to wipe out at least the Railroad and the BoS.

Dude ... Spoilers man. Wtf

My first time around, I betrayed the Brotherhood and the Institute. I had only done two missions for the Brotherhood, before I capped Maxson and went to war with them. Then I killed a few scientists and many Synths while I was in the Institute, used a Laser Gatling I got from a Paladin to kill them. Both the Brotherhood, and the Institute attacked the Castle later.

This is the spoilers and cheats section.

Only after it was moved. It started in the General Discussion.
