Fallout 76 was released a tad early but Bethesda has updated the game several times. The multiplayer mode has attracted a fair number of cheaters using modifications and getting access to items not ordinarily used in the game.
The effect of the issues is that some players have advantages over others which can adversely affect the desire to even play.
We want Fallout 76 to be a happy and healthy world for all players, and we know that there are concerns with players finding and abusing exploits. We’re working hard to find, fix, and address these as they show up. The number of players raising these to our attention has been incredibly helpful in our process of getting to the bottom of these exploits and we greatly appreciate it. We want you to know that we take these exploits and those abusing them VERY seriously.
We are aware that many games have been problematic with cheaters. The larger the size of the game the worst it seems to be. We hope that the experience will be enough for the developers to realize the problem is far more difficult than they realize.
