digging through fallout 76 videos while im bored at work...

found out the vast majority of the game's story/ quests will be told through holotapes and terminals (since there are no human NPCs) that were left from the previous vault explorers 25 years before your player exits the vault
one interview i watched was kinda vague but player vs player combat might only happen on a challenge/ accept challenge basis. like there will be a choice if you want to engage with someone who wants to kill you
