Atomfall is a first-person action survival game inspired by real events, taking place five years after the nuclear disaster at the Windscale nuclear facility in northern England, which occurred in 1957.

Explore a fictional quarantine zone, scavenge for supplies, craft items, trade goods, fight enemies, and interact with other residents of this wild, beautifully rendered part of the British countryside, filled with eccentric characters, mysticism, cults, and ruthless government agencies, as you search for answers and uncover the dark truth about what really happened at the nuclear facility.

• Solve the mystery your way: Through exploration, conversation, questing, and combat, gradually unravel a tapestry of interconnected stories in an environment where every choice you make has consequences.
• Explore a lush, yet hostile landscape: The picturesque British countryside, filled with rolling hills, lush valleys, and secluded villages, is home to countless dangers waiting to be unleashed upon you. Venture fearlessly into ruins controlled by a twisted cult, natural caves, or nuclear bunkers to thoroughly explore this ominous, verdant world. Scavenge for supplies, craft items and weapons, and fight tooth and nail against your enemies!
• Engage in thrilling duels: With weapons and ammo scarce, combine long-range shooting with ruthless close-quarters combat in each desperate life-or-death battle. Watch your heart rate to keep your aim steady, and save enough energy to reach for your cricket bat and deliver the ultimate blow to your opponent!
• See the Windscale disaster through new eyes: Atomfall offers a fictionalized take on a true event from the mid-20th century, using elements of science fiction, drawing from the folk horror genre, and reviving the Cold War atmosphere to create a world that is frighteningly familiar yet completely alien.
