​Rebellion Developments’ latest release, Atomfall, has achieved remarkable success since its launch on March 27, 2025. The game has surpassed 1.5 million players, making it the most successful launch in the company’s 32-year history.

Atomfall is set in an alternate history where the 1957 Windscale nuclear disaster leads to a dystopian Northern England. Players navigate a quarantined region filled with mutated creatures, cults, and remnants of military experiments. The game is available on PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S. ​

Critical reception has been mixed; while the game’s imaginative setting and narrative have been praised, some critics note that combat mechanics are simplistic and quest design can be cumbersome. ​

Despite these critiques, the strong player engagement highlights Atomfall‘s appeal and solidifies its status as Rebellion’s most successful launch to date.​
