Bethesda have recently posted that Fallout 76 should be getting its somewhat more PvP oriented mode soon. It is called Survival and most of the PvP restrictions will be gone, and players will be able to play it with existing characters.
Bethesda have leaned too much into protecting players from griefing in Fallout 76, which resulted in the PvP experience not being enjoyable at all and barely existent. They announced a way to fix it soon after, but now it seems close to release. While Bethesda, didn't offer an exact release date, they did say Survival mode beta will come with the next update.
The mode with PvP restrictions that everyone played in so far will be branded Adventure mode and characters made there will be available in both modes, along with their progression. This means you can immediately pick up your decked out vault dweller in power armour and go to Survival mode for some PvP.
Bethesda said they encourage players to make new characters for Survival, but the only encouragement so far has been in the form of words as there are apparently no in-game incentives for players to make a feeble new avatar that will inevitably clash with power armoured dudes someone brought from Adventure mode.
There is the normalisation with level scaling mechanic though, so lower level characters will have a fighting chance against higher level enemies. Still, it's hard to imagine a dude in a vault suit armed with a pipe pistol beating a heavily armed and armoured war machine , so we would suggest venturing out into Survival with your more advanced characters for the time being.
Bethesda noted there will be no revenge mechanic in Survival, but killing other vault dwellers will award two times the normal amount of bottlecaps. On top of that, the developers are aiming to launch leaderboards along with Survival beta, but they didn't share any details on what they will measure for the moment.
There are some other, smaller scale, changes that Bethesda will be rolling out with Survival, which you can check out on their official website .
