Atomfall: Did You Know About the Event That Inspired the Game?

Atomfall is a survival action game released in 2025, set against the backdrop of a real event that took place in Windscale, Northwest England, in 1957.

In late March last year, game developer  Rebellion  released a brand new project called Atomfall. This was a notable shift after a long period focusing on the  Sniper Elite sniper game series .  Atomfall  takes players to the English countryside in 1960, which is under lockdown due to a nuclear accident. The game recreates a real but little-known historical catastrophe: the Windscale nuclear explosion on October 10, 1957.

Windscale nuclear disaster in the UK

Before the Chernobyl disaster in Russia turned vast areas into a radioactive wasteland, the Windscale event in Britain brought about the worst nuclear disaster in the country's history. On October 10, 1957, workers at the nuclear power plant site on the northwest coast of England, now Sellafield, Cumbria, near the Scottish border, noticed unusual readings from their measuring equipment. After investigation, they discovered that the temperature of one of the facility's two main reactors was alarmingly high, and quickly realized that a fire had broken out inside, seemingly having started on October 7.

They attempted to extinguish the fire, but were hampered by several problems that caused dangerous delays before it was safely put out. Ultimately, the fire was determined to have originated from equipment failure and rushed construction. Things were exacerbated by a series of miscalculations and human incompetence related to proper thermal ventilation for the cooling required by the Windscale plant. Years later, the Windscale fire and the resulting radiation risk were rated 5 out of 7 on the International Nuclear Event Scale, on par with the Three Mile Island incident in Pennsylvania, USA, in 1979.

The British government did not evacuate the surrounding areas, and Harold Macmillan, then Prime Minister of the United Kingdom, sought to downplay the severity by omitting many details from the initial report concerning the extent of the damage and danger to the public. The report, compiled by scientist William Penney, was not fully published until 1988. While no one died in the fire, it released a large amount of radiation, causing hundreds of cases of cancer, both fatal and non-fatal.
