After almost a day long tease showing a humourous Twitch stream of a Vault Boy bobble head and various developer cameos, Bethesda has finally revealed the next Fallout game called "Fallout 76". What little we know about the game is based on the Fallout 76 trailer, which shows that the game takes place on October 27th 2102, the day after party celebrating Reclamation Day, and a Vault 76 dweller is gearing up to explore the surface.
