Atomfall: A mix of Fallout and S.T.A.L.K.E.R.

Atomfall was created by the developers behind Sniper Elite, known as Rebellion, who have crafted a semi-open world that thrives on player curiosity, encouraging exploration and side quests. 

The game was released on 27 March 2025 and has a 78% “Mostly Positive” rating on Steam, with 2,400 positive reviews. While the game features roughly 15 hours of base content, many gamers have called it a fresh alternative to Fallout’s exploration, with some detective elements.

This post-apocalyptic UK game features Fallout and S.T.A.L.K.E.R.-like mechanics, allowing you to loot and scavenge for food, resources, and weapons in ruined cottages, craft weapons like cricket bats from scraps, and barter with the local denizens of Windscale.

Furthermore, every decision you make in the game branches out the story, giving you access to multiple endings and encouraging replayability to see through every ending.

The game features a lush countryside marred by the gritty aftereffects of radiation, with bunkers, foggy villages, cults, and caves to explore and loot.

Over the past year, Atomfall has received numerous updates that overhaul traversal and improve combat, along with two storyline expansions called The Red Strain and The Wicked Isle.

With numerous patches addressing initial bugs, new story add-ons, and a 50% discount, now seems like the best time to jump into Atomfall, especially if you’re craving a Fallout-like game set in the UK.
