Hi there,
There is a problem I have with the main story;
When I had to go to the Fort, I made a mistake and brought Boone with myself. So they got hostile to me. I continued, but it the Fort itself I decided to get back and I just got outside and fast traveled to another place.
I realize NOW! that it's so hard for me to fight against the whole Fort. so please tell me how can I side with the Legions again?
P.S: forget the last savegame, I played near 3 days after that!!

Well depending on which point you are at in the main quest, your main factions reputation if negative gets reset to neutral (I'm not stating at which point in the general discussion forum, as I think I've been spoilerish enough already, but will lob a pm your way saying at which point.).

thanx a lot !
