During QuakeCon 2018, Bethesda game director Todd Howard, development director Chris Mayer, and project lead Jeff Gardiner were part of a Q&A session centered on the upcoming Fallout 76.
While we know a fair amount about the setting and general gameplay mechanics, the Q&A yielded a few interesting new bits of information about customization, what you lose in death, and a uniquely brilliant way of dealing with online trolls and griefing.
Probably the most significant detail we learned was how the game will handle trolls and players who grief others online. In order to engage in PvP, players can attack someone and do significantly less damage than they would against an AI-controlled opponent. Should the other player choose to engage, then PvP will have been initiated and no punishments will be given.
