Since its reveal, Atomfall has been called "British Fallout." The vibes are certainly there, but overall, it's a very different kind of game with the only real similarity being the alternate history approach to an apocalyptic event. Even then, Atomfall's real-world Windscale incident is much more localized than the Great War in the Fallout universe, but anyone who loves a good post-apocalyptic game owes it to themselves to check out Atomfall. After 90 minutes with it, it became clear that developer Rebellion's action-adventure game is something special.
