I just raided the gunrunners building and pretty much killed everybody for the crimson caravan and when i got back to mccarferty shes said that the GR will seek revenge, so my question is:

Will they actually come after me like CL/NCR assassins?

Go to Novac and place booby traps under the bridge "mines"

which is to your left when you exit the town go down the far right road backwards the T Rex statue should be on your left view
after going far enough go back to the underpass "the bridge" toward the left side where your mines should be

the assassins will spawn and be coming towards you
if done right you'll take almost all of em out leaving only 1 enemy for you to take out with some frag grenade

Probably.. I haven't started any missions for the caravan so damn you spoiler!! lol jk,,, But the way i see it.. GR assassins = Battle armor and kickass weapons...



You evil bastard lol!
