The Main Legion force on Fallout New Vegas is located at the Fort. Which is the fully owned Legion Area throughout the game, except for Cottonwood Cove.
No. Once you help either Yes Man, the NCR, or Caesar's Legion take over New Vegas, whoever you helped is who you're sided with.
Just play through the game and some guy ill come up to you and say "Caesar had wished to see you in him camp. All crimes against the legion are now forgiven" or something like that... then you go to Caesar and do a bunch of quests for him... that's all
Evil.
No you cannot be idolized by EVERY faction in fallout new vegas. At some point you will either be Vilified by the NCR, or the Legion, Or by both. If you side with the NCR then it will eventually start the quest Beware the wrath of Caesar! where it will make you vilified by the Legion if you do not start to side with them. It is the same with the Legion where it will start the quest Dont Tread On The Bear! Finally if you side with Mr. House then it will start both of those quests
Simply kill any recruit member of the legion. almost all legion recruits carry machete.
The mission Arizona Killer is available when completeing the game for ceasars legion.
If you choose to be neutral or good I go with the NCR hands down If you choose to be evil in the game stick with the Legion In my opinion I would go with the NCR
You can't. It's not like the NCR or the Legion. You can't do anything to up your rep with the casinos.
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
The NCR's overall leader is President Aaron Kimball. The military effort against the Legion, is General Lee Oliver.
You can get Rex by talking to The King, in Freeside. And he will ask you to get his buddy a new brain. (Rex) And then you can get him the Legion brain, because it is my favourite, and probably the best. :)
