I'm roleplaying FNV with a cowboy courier and one decision of this build is when companions are killed, they stay dead! That's it, no reload or second chances. This make me very carefull when engaging creeters or enemies and also make the game a little bit more tactical, because you need to weigh your chances and study more the scenario before entering the combat. But I made a mistake. One of my perks is "And Stay Back", a perk that make a shotgun knock-down an opponent, just like Knock-Kock/Oh, Baby! do. But I think I gone over my head, because I was feeling immortal and untouchable. Well, my great work made me losing one of the best companions for my build, Cass. This is her grave and this is the motherfucker that kill her. I forgot how unforgivable the FO world is. Shit!
