Fallout 3 is a post-apocalyptic, action role-playing game developed by Bethesda Game Studios for the Xbox 360. Set in the ravaged Washington D.C. area, players emerge from an underground bunker, Vault 101, to explore a wasteland filled with dangerous mutants, hostile factions, and the remnants of humanity. With a blend of first-person shooter elements and open-world exploration, players can customize their character's abilities, make moral choices that influence the story, and engage in tactical combat. The game's immersive atmosphere and hybrid gameplay define its unique dystopian adventure genre.
