The trend of turning dystopian drama series into reality competition continues.

Amazon has handed a greenlight to Fallout Shelter, a series based on its Ella Purnell-fronted drama. The project comes from Studio Lambert, the company behind Netflix’s Squid Game: The Challenge, a reality series based on the streamer’s hit Korean series.

The ten-part series is based on the eponymous video game extension, which came out in 2015. Set inside Vault-Tec’s bomb-proof vaults, Fallout Shelter sees a group of contestants take part in “escalating challenges, strategic dilemmas, and moral crossroads” as they chase a cash prize.

It comes as the second season of the drama series, which comes from Jonathan Nolan and Lisa Joy, is in the middle of its run, having premiered in December.

The drama, which also stars the likes of Walton Goggins and Kyle MacLachlan, is the story of haves and have-nots in a world in which there’s almost nothing left to have. Two-hundred years after the apocalypse, the gentle denizens of luxury fallout shelters are forced to return to the irradiated hellscape their ancestors left behind—and are shocked to discover an incredibly complex, gleefully weird, and highly violent universe waiting for them. It scored an early season three renewal.

Studio Lambert is producing Fallout Shelter with Nolan and Joy’s Kilter Films, in association with Amazon MGM Studios and Bethesda Game Studios.

Executive producers include Stephen Lambert, Tim Harcourt, Jack Burgess, Toni Ireland, Stephen Yemoh, Stephen Lovelock and Amina Badresingh for Studio Lambert with Abi Lambrinos as executive in charge of production; Nolan, Joy and Athena Wickham for Kilter Films and James Altman and Todd Howard for Bethesda Game Studios.
