Two Brothers Pictures has announced a television adaptation of Atomfall from Rebellion®, the UK‑based post‑apocalyptic survival‑action game that won the award for Best British Game at this month’s BAFTA Game Awards. The series will be developed as a co‑production between Two Brothers and Rebellion.
Inspired by the real‑world Windscale disaster of 1957, Atomfall was developed from an original idea by Jason Kingsley CBE and offers a distinctly British take on the post‑apocalyptic genre. The story is set within a single Quarantine Zone in the Lake District - a walled, militarised area established after the nuclear incident. While the outside world is assumed to continue as normal, life within the zone has deteriorated into something far stranger.
The video game follows a protagonist who wakes up inside the Quarantine Zone with no memory of how they arrived. As they search for a way out, they become entangled in a web of competing factions, encountering an eclectic cast of characters each with their own agenda. Drawing on the legacy of classic British sci‑fi, with elements of folk horror, Atomfall blends nuclear paranoia with ancient mythology.
Since launch, more than 3.7 million players globally have explored the world of Atomfall, and the game recently won Best British Game at BAFTA Games Awards 2026. The TV adaptation will expand on the game’s mythology while remaining faithful to its tone, themes and British roots.
Harry and Jack Williams, writers and Executive Producers, Two Brothers said: “Atomfall has such a distinctive British tone and setting, and it’s been a real joy developing it alongside the Rebellion team - especially as two brothers working alongside two brothers (Jason Kingsley CBE and Chris Kingsley CBE - co-founders of Rebellion). There’s something very exciting about expanding this strange, unsettling story for television.”
Jason Kingsley CBE, CEO and Creative Director, and Chris Kingsley CBE, Co-founder and CTO of Rebellion, are both Executive Producers on the project: “We are delighted to be partnering with Two Brothers to bring the world of Atomfall to television. Harry and Jack demonstrated a clear love for Atomfall and talked about their own particular endings when they were playing the game. It is always exciting to work with people who share the same passion for creating and telling great stories and we are sure that this partnership will help to deliver a television series that will delight fans of the game and beyond.”
The series will be written by Emmy and Golden Globe winning producers / writers Harry and Jack Williams (Fleabag, The Assassin, The Missing, Baptiste, The Tourist), and Executive Produced by Harry, Jack and Alex Mercer (The Assassin, Maya, The Tourist, Doctor Who) for Two Brothers. For Rebellion, Jason and Chris Kingsley (Sniper Elite 1-5, Zombie Army 1-4, Dredd, Schools Out Forever, Rogue Trooper) will Executive Produce alongside Ben Smith (Schools Out Forever, Rogue Trooper) .
