you can use non lethal ammo and weapons. it knocks them out instead of killing them
it means dont kill anything unless it is absolutely needed to complete the game
ahh, you see, that was beyond my knowledge that there actually was non-lethal rounds in FO:NV. That ...
that makes me want this game incredibly badly. Non-lethal ammo/unconsciousness is awesome! perfect for fallout! they had it in 1, I wondered why they took it out of 3 (excluding paralizing palm)
man I'm super stoked now! thanks!
edit: also, i'd assume you'd prettymuch have to skip most/all side quests, thus limiting your chances of running across a quest that requires you to kill something. I mean, you wouldn't HAVE to, but.. i dunno.
I'm definitely trying this though. maybe for my third run (first run will be normal with guns, second hardcoe and melee/energy weapons, and third with whatever is non lethal

)
