Become engrossed in a huge apocalyptic open world in Fallout 4 for PS4. Hundreds of years after nuclear weapons destroyed the Earth, players will wander the irradiated wastelands of the Commonwealth - the city of Boston and its surrounding areas, which makes for one of the most rich and detailed open worlds in gaming. Fallout 4 takes the sandbox formula of developer Bethesda, famous for The Elder Scrolls V: Skyrim and Fallout 3, and refines it in multiple ways, resulting in the largest and most detailed RPG of the past few years.
