Fallout is a series of post-apocalyptic role-playing video games set in a retro-futuristic world devastated by nuclear war. Players explore vast open-world environments, complete quests, and interact with various factions while managing resources and character development. The series is known for its dark humor, rich storytelling, and unique art style, which combines 1950s aesthetics with a dystopian future. The franchise began with the original Fallout game in 1997 and has since expanded to include multiple sequels and spin-offs, such as Fallout 3, Fallout: New Vegas, and Fallout 76. Each installment offers players a chance to experience the consequences of nuclear fallout and the struggle for survival in a harsh, irradiated landscape.
