Fallout: New Vegas is a post-apocalyptic open world video game set in a retro-futuristic 1950s-inspired California and Las Vegas wasteland. The player assumes the role of a courier shot in the head who must discover who attacked them while exploring the irradiated former cities, fighting mutants and enemies. The game received praise for its original story and expansive map, though some criticized technical issues with the aging Gamebyro engine.
