I am at the final part of the King's Gambit quest. I have taken the path of telling Colonel Hsu to give extra supplies in return to decreased attacks. However, when I go to the School of Impersonation, it is swarming with NCR troops. I think that is supposed to happen, but when I tell The King about the situation, and he agrees, Pacer gets angry and attacks. I have read that this is normal, but the troubling part is that when he attacks, the rest of the Kings attack as well. The King himself tries to run away, until I kill Pacer, which then gives me Freeside Infamy and make him hostile. Even when I leave the School of Impersonation, the Kings in the streets attack me on sight. Is this supposed to happen? I can't revert to an earlier save, because I don't have one. How can I finish this without killing all of the Kings?

Try not firing your weapon, and let NCR and co. kill Pacer.

It worked! Thanks! A few of the other Kings became hostile, and they tried to fire on me, but they were wiped out by the NCR. I can't believe I didn't think of this!

Thanks a lot.

It's a bug for sure. When I did it, only Pacer went hostile, and I shot at him (didn't get the killing blow) without repercussions. A few of the other Kings died too, but I'm not sure if Pacer killed them or if they supported him and were killed by the NCR troops.

In my game I am able to help kill Pacer, and all of the Kings do not go hostile on me. But I know from having worked a follower issue for my mod in there, that, it changes the situation a bit if the player fights during that fight.

In my first play through when Pacer went hostile I shot at him and killed him causing all the other Kings to become hostile towards me. I loaded the quick save from entering the school and this time when he went hostile just stood back and let the Troopers do all the killing and everything was fine. Granted the King was a little sad but everyone was cool and I think I got some Freeside fame. I don't remember though so don't quote me on that one.
