I'm hunting those NCR hit squads too lol only got the one warning, but I just came back from finishing LR. Level 21 in 13 hours, and I have some nice boom sticks now. I want to find some more Hunting Revolvers to repair my Ranger Sequoia regularly. Avoiding Jury Rigging this time around, even though it is awesome. Going with a light armor character and I need to get my criticial perks and DT up first.
Hehehe, wait.. wow.. you beat LR in thirteen hours at level 21? GAWD, -envious-
ANYHOW, I still if I was you would get like ED-E and (Seeing how hes the only one that doesn't care about the Legion unlike Boone and Arcade, then Veronica cause the whole BH quest... )Raul. Then just hide in one of the what ever places, and let Raul and ED-E slaughter 'em.
Thats what I did when I was in one of those stages at a medium level. x)
Meh, I think I got a warning too.. not sure if I decided to kill 'em all when they turned away, or what ever.
