As soon as Bethesda announced that Fallout 76 would feature PvE and PvP elements, players had concerns about griefing.
While most of your character build in Fallout 76 will be up to you, dependent on how you assign SPECIAL points and Perk cards, spending time in irradiated areas comes with the chance of undergoing a mutation that alters your character. Bethesda's creative solution? "Turn the assholes into interesting content".
One of the biggest worries Fallout fans have in this online version is how PK, short for player kill, is enabled everywhere.
What Else Did We Learn About 'Fallout 76?'
Repeatedly killing other players if they haven't attacked you will mark you on the map. There will be a perk system in the form of cards that can grant additional skills that you can switch on the fly and even share with others. And presumably if the aggressor is of a high level, that small damage could be enough to kill any low level player quickly, thereby hurting their experience.
The QuakeCon 2018 panel also revealed that there will be a revenge mechanic in Fallout 76. The reward, of course, will be higher for trolls with higher in-game levels. Those who are wanted will be clearly marked for other players to see whereas player markers will be removed for griefers so they won't be able to see other players coming for their heads. When you die, the only outcome is that you drop the junk you're collecting, which is used to build. Armor and weaponry isn't lost upon death, so the only decision you have to make after dying is whether you want to go back and collect your resources.
When players die in Fallout 76, they will not lose their equipped weapons and armor. If you engage with players with a vastly different level than your own, the power levels will normalize so there's a more balanced confrontation. Players will start with one point in Strength, Perception, Endurance, Charisma, Intelligence, Agility, and Luck, and every level they can add another point to one stat.
