Windscale

CEO Jason Kingsley tells BBC Newsbeat he was walking in the Lake District when the idea of using the real-life Windscale story "as a trigger point for a fictionalised version of the disaster" began to take shape.

Windscale was eventually renamed Sellafield and produced nuclear power until 2003.

Although the Windscale fire was "very serious", Jason says it's not something that is especially well-remembered, even among locals.

Oliver says he's glad the game has taken its inspiration from Windscale and is drawing attention to the area, as well as switching locals on to their history.

But fewer are aware of the Windscale fire.
