Atomfall is a survival-action game set in the rolling British countryside. Atomfall is inspired by the real-life events of the 1957 Windscale disaster in the North of England, picking up the story five years after the fire in a fictionalized quarantine zone.

Opening in the style of a classic 1950s news reel, this latest trailer offers a closer look at Atomfall’s setting in the North of England. Atomfall is inspired by the real-life events of the 1957 Windscale disaster and the story picks up five years later in a fictionalized quarantine zone that encompasses a rolling countryside, valleys, caves and even a picturesque English village.

But this picture-perfect postcard setting is a hostile landscape that hides a dark mystery. To get to the bottom of what happened at Windscale, you will need to navigate military encampments, delve through abandoned bunkers below ground and risk your life in Pagan ruins. Your trusty metal detector will also help you uncover a few secrets buried beneath the surface.

Central to the dark mystery is the host of eccentric characters and cryptic organizations that inhabit the quarantine zone. These individuals have been cut off from the outside world for years and left to their own devices, and are anything but normal. Your interactions with them are important and will shape your journey. But be careful, not all survivors are friendly, and you will need to master an array of ranged and melee weapons if you are to survive.

Rebellion announced that Wicked Isle, a story expansion for Atomfall, will launch across all platforms on June 3, 2025 at £14.99, €19.99, $19.99.

The expansion adds a whole new location to the game, with its own set of characters and enemies as well as additional leads, weapons, skills, items and multiple new endings for the main game.

Drawing on the folk horror elements of the game for inspiration, the story expansion is set on Midsummer Island. To cross to the island players must talk to the boat-keeper who can be found on the jetty in Wyndham Village. He will give you information about the island as well as your first Lead.

“Midsummer is located close to the Windscale Atom Plant and as a result the levels of infection in both the people and environment are higher than on the mainland,” explained Ben Fisher, Head of Design at Rebellion. “You are going to meet new enemy factions including pirate bandits and infected druids. To help you survive there are new weapons to be found on the island including a devastating Blunderbuss shotgun, a new bow, cutlass, daggers and the Beekeeper’s Staff. You will also be able to acquire new skills which will aid you on your quest as well as an upgraded metal detector which will enable you find even more loot caches.”

The Leads you uncover in Wicked Isle will open a variety of story treads, some of which create new potential endings for the main Atomfall game.
