A large-scale fan modification for Fallout 4: Game of the Year Edition. The player finds themselves in a dark and atmospheric version of the British capital, where ancient traditions clash with the new realities of a world that has survived a nuclear catastrophe. London is depicted as a place plunged into chaos, with unique factions, style, and culture, distinct from what has been encountered in the main series. The modification offers a new adventure with entirely original characters, quests, and locations that reflect the spirit and history of London, adapted to the harsh conditions of a post-apocalyptic future.
