Atomfall, a Fallout-like open-world action-adventure game set in post-apocalyptic UK, is currently 50% off on Steam until March 19, 2026, offering players a unique blend of exploration, survival mechanics, and branching narratives.
If you're craving a Fallout-like experience but want something set in a different world, Atomfall might be exactly what you need. This post-apocalyptic open-world action-adventure game is currently on sale for 50% off on Steam, dropping the base game's price to $24.99 from $49.99. The discount runs until March 19, 2026, so you'll want to act fast if you're interested.
Developed by Rebellion, the studio behind Sniper Elite, Atomfall puts you in the shoes of a character who wakes up in the quarantined Windscale area of Northern England with no memories of the past five years. Your journey to uncover what happened unfolds in a semi-open world that rewards player curiosity and encourages exploration of side quests.

The game launched on March 27, 2025, and has maintained a 78% "Mostly Positive" rating on Steam with over 2,400 positive reviews. While the base content runs roughly 15 hours, many players have praised it as a fresh alternative to Fallout's exploration formula, with some detective elements woven throughout.
What makes Atomfall particularly interesting is how it blends mechanics from different games. The scavenging and looting systems feel reminiscent of both Fallout and S.T.A.L.K.E.R., allowing you to search ruined cottages for food, resources, and weapons. You can craft weapons like cricket bats from scraps and barter with the local denizens of Windscale. The game's decision-making system branches the story in meaningful ways, giving you access to multiple endings and encouraging replayability to experience every possible outcome.
The setting itself is a character - a lush British countryside marred by the gritty aftereffects of radiation. You'll explore bunkers, foggy villages, cults, and caves, each area filled with its own secrets and dangers. The atmosphere captures that post-apocalyptic tension while maintaining a distinctly British flavor that sets it apart from American-based post-apocalyptic games.
Since launch, Atomfall has received numerous updates that overhauled traversal and improved combat mechanics. The developers have also released two storyline expansions: The Red Strain and The Wicked Isle. These additions, combined with patches addressing initial bugs, have helped refine the experience considerably.
For those interested in the complete package, the Complete Edition Bundle is also on sale. After a 50% discount on top of a previous 12% discount, it's currently priced at $41.32, down from $82.68. This bundle includes five DLCs that expand the base game's content significantly.
The sale includes multiple editions:
- Standard Edition: $24.99 (originally $49.99)
- Deluxe Edition: $34.99 (originally $69.99)
- Complete Edition Bundle: $41.32 (originally $82.68)
Whether you're a fan of post-apocalyptic settings, enjoy games that reward exploration and curiosity, or simply want a Fallout-like experience with a British twist, Atomfall offers a compelling package at its current sale price. The combination of its unique setting, branching narrative, and survival mechanics makes it worth considering, especially if you've been looking for something to scratch that post-apocalyptic itch while waiting for the next big Fallout release.
