Many gamers might not be familiar with the Windscale nuclear accident, but this real-life event served as the inspiration behind a game that imagines a very different kind of Chernobyl—right in the UK. This catastrophe could have rendered all of Britain, or even Western Europe, uninhabitable. Fortunately, a mix of luck and swift action prevented the disaster from spreading. But what if things hadn’t gone so well? That’s exactly the question that the game Atomfall tries to answer. While the game doesn’t directly portray the incident, its entire story is clearly inspired by it.
What Was the Windscale Incident?

On October 10, 1957, a fire broke out in the first reactor unit of the Windscale nuclear facility, located near Cumberland in northwest England. Globally, the accident was rated at level 5 out of 7 on the International Nuclear Event Scale. It resulted in over 250 cancer cases, sadly with around 100 fatalities.
Although not as catastrophic as Chernobyl, it remains the most serious nuclear disaster in Western Europe. The fire caused enormous human and financial damage. Many people lost their lives, and in just a few hours, the UK’s nuclear technology and energy strategy were set back by years. It’s safe to say this incident left behind massive destruction. But Atomfall dares to ask: What if the disaster had been even worse? What would have happened if the nuclear fallout had escalated beyond control?
Why Windscale as the Inspiration for Atomfall?
By now, most gamers are familiar with the nuclear quarantine subgenre—games where players are trapped in radioactive zones, struggling to survive. There are countless titles in this category, many of which share similar mechanics and aesthetics.
Yet, surprisingly, none of them had explored the world’s first nuclear disaster—until now. The Windscale fire had the potential to change the entire future of nuclear energy, yet it was largely forgotten. The developers behind Atomfall found this troubling. Though Windscale wasn’t the deadliest incident, it was the first. Because the casualties were fewer than in other disasters, it was largely ignored. That’s why the creators of Atomfall chose to craft a what-if scenario—an alternate reality in which Windscale turned into a much more devastating event.
No Need to Know the Real Incident to Enjoy the Game
One important thing to remember: Atomfall is not a historical documentary. It’s not a retelling of the Windscale fire. The developers were inspired by it to create a fictional, post-apocalyptic world. Sure, if you know the true story, you’ll appreciate the game’s themes more. But you absolutely don’t need prior knowledge to enjoy the experience.
Interestingly, many people blame the British government of the time for the lack of transparency. Officials downplayed the disaster, constantly claiming there was no threat, despite clear evidence to the contrary. Today, we know these reassurances were false, driven by Cold War politics. That’s one reason why Windscale isn’t commonly remembered among other nuclear disasters.
As you progress through the game, you’ll slowly uncover references and facts about the actual incident. While the game is fictional, players unfamiliar with Windscale will still get the chance to learn more about it through in-game exploration.
Atomfall’s World Is Cut Off from the Outside
The events in Atomfall take place five years after the fictional version of the Windscale incident. In the game’s timeline, the disaster is far more severe than in reality. The government’s reaction mirrors the Soviet response to Chernobyl—they completely sealed off the affected area and placed it under total quarantine.
No one inside the contaminated zone can communicate with the outside world. As a result, the game’s story is focused solely on the events within this isolated area.
Of course, it would’ve been fascinating to see how other countries reacted, or how the incident influenced global nuclear energy development. But it’s understandable that the story stays centered on the quarantine zone, providing a tighter, more immersive narrative.
How Much Is Atomfall Inspired by Windscale?
Atomfall is not a historical simulation, but the Windscale incident served as a foundation for its setting and mood. The developers used the real-world location of Cumbria, England to build the game’s environment. While the characters and events are fictional, the game is rooted in the question: What if the Windscale fire had spiraled out of control?
To explore that idea, the developers blended science fiction elements with real-world geography, creating an experience that feels both imaginative and grounded. As you explore the game in first-person, you’ll walk through towns modeled after real places, encountering criminal gangs, mutants, survivors, and other entities that feel disturbingly plausible—if not in reality, then certainly within the logic of this alternate history.
