I may have pissed the NCR off now they send troops after me but i want to live in vegas in peace with them any quick ways to get them to love me?

Nope, sorry. Once you piss off a faction, it's pretty much set in stone.

Great looks like my home in vegas is gone and now they all gotta die thanks anyway though

You could wear some NCR faction armour, granted you weren't wearing it when you got them hating you? If not, get some wear it, do a few quest till your neutral..... :celebration:

Looks like you're gonna have to go make some friends across the river :thumbsup:

Enter the New Vegas strip as fast as possible. An NCR trooper will give you amnesty for your crimes (how did you piss them off, anyway?).

You could always disguise, just don't get to close to guard dogs or actualy guards. They see right through that thing....

For the most part, once you piss off a faction, they will hate you. Thats why I am extra careful on which faction I hate the most.
