yes.
You can kill people and steal their stuff, and sell them. :)
None of the Fallout: New Vegas expansions allow you to continue after you beat the game.
The brotherhood outcast will come after you... but don't worry it's not much of a problem as along as you have some laser rifles or assault rifles... WORD of advice. If you are going to kill the outcast... make sure you raid fort independence to get some powerful weapons like the gastling laser.. or PLASMA rifles. ( this only applies the fallout 3 in dc and not fallout 3 new Vegas)
if you try to attack and kill him then every person in the tops will shoot at you i recommend that you finish the quest talent pool then kill Benny but when you do every time you go into the tops the people will attack you on sight i know this cause i did it
Just don't do anything to hurt that faction. I.e. steal from them, kill their soldiers, ect.
Simply kill any recruit member of the legion. almost all legion recruits carry machete.
when you attack him he attacks you but if you kill him it says he is unconscious and he gets back up and stops fighting you
no if you kill them the die and stay dead. You cannot take weapon mods of dead shopkeepers if that is the reason you kill them. and you can't kill the vendertron and the gun runners shop.
they will kill any one who is not an ncr just kill a ncr and take his clothes You've probably directly attacked one of them by accident.
Firstly, don't kill him at the Topps. He'll make a deal with you, then flee, sending his goons to kill you. He will travel to the Fort, where he will be captured by Caesar. You are given the option on what happens to him, you can free him or give him a bobby pin and a stealth boy so he can escape - either way it means you have to kill Caesar and fight your way out through the Legion troops.
No, Fallout 3 is not food. If you ingest it, it may kill you.
