In Fallout Shelter, you play as one of the officers in your very own vault, trying to foster happiness among your vault dwellers while keeping them safe from the radiation and monstrosities of the Wasteland that awaits outside your utopia. You will need to assign your dwellers to tasks, manage the vault’s resources, and keep everyone safe from threats. Keep in mind, whichever of you can inspire the most happiness will win the hearts and minds of your dwellers for the coming election of the new Overseer!
