A Fallout 76 bug is currently preventing players from launching the nuclear weapons the game is known for. While it’d be nice to see a bug that prevents total nuclear annihilation become a feature in real life, if players can’t launch nukes in Fallout 76 they can’t initiate high level ("endgame") content. If high level players can’t play that content, there’s no reason for them to log in to Fallout 76 unless they want to reroll a new character. It’s like if World of Warcraft players woke up one morning and suddenly couldn’t join raids.

Launching nukes is the whole point of Fallout 76, a feature that stands in stark contrasts to the franchise’s anti-nuclear war roots. To launch the face-melting ICBMs, players collect code pieces they decrypt and input into a launch terminal in a silo. It’s supposed to be a hard process, but players quickly streamlined it and the nuclear codes are typically public information hours after they reset every Monday at 4PM Pacific.
