A disaster epic set in the rolling hills of the Lake District won the award for best British game at the Bafta Games Awards.
Atomfall, produced by Oxford-based Rebellion, is based on an alternative history of the UK's worst nuclear accident - the 1957 Windscale fire in Cumbria.
It is set in a sci-fi inspired timeline where the area surrounding the plant has become a quarantine zone.
Game designer Ben Fisher told Radio Cumbria that winning the Bafta on Friday night had been "absolutely mind-blowing".
"When you're making a game you've no idea whether people are going to really connect with it or not," he said.
