Can I still get the NCR to take back NCRCF if I am hated by the Powdergangers?
I tried going in in there outfit, but the leaders still attack me...

It's very difficult but I have done this.

You need to sneak in and then, at the head honcho's office, RUN to him and talk before he turns hostile. You'll have to do that a couple of times to complete his missions so that you get the option to either help them or help NCR take over. After talking to him, he turns hostile and you'll have to run the hell out of there so it is made easier if you stealth kill everybody else in the facility.

It is possible, but it's a big huge pain in the ass.

Stealthboy can probably help a lot. You need few of them however.

I wouldn't brother, unless just have just started you may as well start again.

Go in kill them and PRETEND NCR thanked you. :celebrate:
I pretend alot.... :whistling:

I helped the NCR take the prison back (did "I fought the Law" and betrayed the gangers by helping Hayes) but the radio says the NCR attack failed even though all the gangers are dead and the towers and Admin office are occupied by NCR troops.

And sometimes on completion the alarm never stops.

I just kill everyone....I wish the questline / scripting triggers for the prison worked better though. Wasn't so quirky you might say.

Need every XP I can get with a 50% slower leveling mod.

Like somebody already stated...I just pretend.

Yeah, I hate that place. I went in to recruit the Sheriff for Primm and was shot at. Now, I make the robot in Primm sheriff even though I hate his friggin' voice and that when outside of the Vicki and Vance he still acts like he is inside. I don't even go near the prison. I have plans on bringing Boone, ED-E, Victoria over to it and wiping the lot of them out as soon as possible.

PS: I'm on PC using mods to have multiple followers.

You do know the powder gangers being hostile has no effect on the ability to make Myers sheriff right?

You do realise that you can 'disguise' yourself in Powder Gang clothes, yes?? This will be enough talk to the guy for Primm sheriff without getting shot at... Won't fool the PG boss and his pals, though, so stay out of the Admin building.

Look, this Powder Gang thing is easy, even if you support Goodsprings in the shoot-out.

1 - Make sure you get all the Goodsprings support possible.
2 - Make sure you have a good condition silenced and scoped rifle.
Go get Ratslayer (Broc Flower Cave) if you don't want to spend the caps on modding a Varmint Rifle
3 - When the 'high-noon' event triggers, do the following:
a) leg it down the hill from the petrol station to the rusted truck and bushes on the right-hand side of the road, just before the shop and bar. you must do this before the gang arrives and sees you.
B) go into sneak, get your rifle out and scope the road ahead where the gang appears.
c) as soon as you see the gang, stay hidden and start sniping. No need to shoot everyone ,just cull 1 or 2 and help out a bit on Joe Cobb if you can
d) DO NOT MOVE OR BREAK COVER until it is over and you see the faction rep info - Idolised by Goodsprings and Shunned by Powder Gang

Ringo will then come to you with caps and thanks. Then, check to see that Trudy and Sunny are still alive. If everyone made it, you are good to go and can walk into NCRCF without any problems or disguise. If Trudy or Sunny is killed it is up to you if you want to re-load and try again. If you get any other faction rep besides Shunned, you need to re-load and try again.

Remember one thing, if you decide to go after any other Powder Ganger's before going to NCRCF, make sure to keep hidden and snipe well at range, otherwise you will shift to Hated or Vilified rep and will be shot at in the NCRCF

That's a bit convoluted. You can just toss a grenade or two into the lot of them as they approach Goodsprings, which softens them up but won't kill any of them. Even if you kill one you'll still get Shunned and, therefore, be able to talk to Eddie and get his quests.

Or you can just "soften" them by fire while drawing their fire upon you so others have better chance to survive. Just make sure you don't kill (finish) any one of PGangers. If you accidentally kill one, you probably still can get away from it with Shunned reputation which is just ok. Then just avoid other gangers until you visit prison. You will be offered truce and should not be attacked unless you attack yourself.

Of course you can always sneak/kill any ganger without reputation loss.
