There is an easier way which means that you don't need to kill them, use the monorail at mcarrans camp ? I think that's what its called, this is far easier and you area able to access the gate all the time once doing it once. So use the monorail within the building, go up the stairs and there will be a sign saying monorail, with 2 NCR guards guarding the door, just run through wait for it to load and then enter the monorail which will take you to the strip, I hope this helped
Why the 2 monorail guards always turn hostile? My relationship with NCR is Accepted. My weapon was not drawn. Obviously my armor is not faction related because nobody attacked me until I walk near the monorail doors at Mcarran camp.
The Gate to the strip became locked after I completed the 2 Omerta missions where you need to recover the weapon cache in Fiends territory and the Chlorine gas. I am on NCR questline so I don't want to fight them. Shooting the 5 securitron in front of the gates to get the key is the only way. You have to be careful since those inside the gate will attack you as well. Don't shoot at the NCR MP if you don't want to loose NCR fame.
I read elsewhere in Fallout wiki that you need to have NCR uniform on to use the monorail in a peaceful manner. Can anybody confirm that?
