Fallout 76 is a post-apocalyptic multiplayer online role-playing game developed by Bethesda Game Studios and published by Bethesda Softworks. It is the newest installment in the Fallout series (ninth overall) and released on Windows, PlayStation 4, and Xbox One on November 14, 2018.

Before the game released, game director Todd Howard explained how Fallout 76 at launch was intentionally not meant to be the final version of the game because it was meant to be an evolving live game that would receive many updates based on player feedback, similar to many other online games. Todd mentioned it could be a very different game ten years in the future. The 2018 version was merely a "starting line" as a result. Fallout 76 receives free seasonal updates via patches and new content is planned for at least roughly 2027. In 2024, Bethesda announced that Fallout 76 has reached 17 million players. Unlike other MMOs, no monthly subscription is required to play Fallout 76.

According to the game's former designer Mark Tucker, Fallout 76 will eventually have its own "ending" of sorts with Mark stating, "We have a story in the game that we have always intended to tell over a longer time span."
