According to a thread on Reddit, Fallout 76 largely resembles Fallout 4 internally, which makes it relatively easy to hack. The game reportedly does no file integrity checking before launching, critical features like collision detection run client side, and client/server communication is largely unencrypted. The poster cites a relatively innocuous mod that was already uploaded to the Nexus, which shows you the "sweet spot" in Bethesda's lockpicking minigame. Angry Reddit threads like this pop up all the time, but what makes this one particularly interesting is Bethesda's official response on IGN. While they say that "many" of the claims are untrue, they don't outright deny them either, and even single one of those listed issues could be devastating to the final game. "Many of the claims in the thread are either inaccurate or based on incorrect assumptions. The community has however called to attention several issues that our teams are already actively tracking and planning to roll out fixes for. Our goal is always to deliver a great experience for all our players. Cheating or hacking will not be tolerated. We know our fan base is passionate about modding and customizing their experience in our worlds and it's something we intend to support down the road."
