Few games throw you to the wolves as quickly as Atomfall. The latest from Sniper Elite’s Rebellion Developments, Atomfall is a post-apocalyptic survival-action game taking place in Northern England. Unlike Rebellion’s previous titles, Atomfall heavily focuses on narrative—primarily the goal of unearthing the mystery of the disaster at the Windscale Atom Plant.
The game uses the mostly unknown but real nuclear disaster as a jumping-off point for a compelling mystery and investigation. This conundrum is the highlight of Atomfall’s twenty-ish hour runtime. Each element smartly focuses your playtime on the central process of discovery.
What makes the mystery so compelling is how little guidance Atomfall gives you. After emerging from the bunker with no memory and vague instructions to “find The Interchange”, Atomfall’s world is almost entirely open. Bar those opening moments and the general shape of the conclusion, each player will have a unique journey; finding ‘leads’ in their order and tackling objectives with vastly different information and resources.
Leads are both a narrative element and an innovative mechanical feature. At its core, Atomfall is a game driven by investigation, one propelled by player curiosity. While wandering the lush hills and beautiful vistas, you’ll uncover clues hinting at the wider narrative. Leads organise this information into broad topics to serve as a direct reference for your examination.
Importantly, leads rarely give quest markers. While certain characters send you to particular locations, the onus is on you to be thorough in your investigation. Many of these leads become deeply interwoven, with the majority linking to the central mystery of the zone. If one element of Atomfall inspires other games, I hope more put their faith in players following leads rather than chasing quest markers.
“Player curiosity is Atomfall’s nucleus…”
The Lake District quarantine zone is an amazing interlocking puzzle box, where layers progressively pull away to reveal hidden depths. World design in Atomfall is top-tier, and the looping dungeons and wider connections that crisscross the game world are impressive and immersive without being overwhelming.
Ultimately some of Atomfall’s reveals play with familiar tropes, and there are some predictable elements at play. But the specifics of this particular science gone wrong story were engrossing, and I was compelled to resolve a variety of leads despite having a clear idea of how to progress towards the end game. This did result in some long runs towards the end, but the map is a reasonable size so this was mostly a minor inconvenience.
Atomfall’s greatest strength is the way it lets the player explore this story and craft their journey of discovery. Player curiosity is Atomfall’s nucleus, with each element working to push you towards observational and investigative play. While the narrative naturally unfurls as you investigate further, mechanical progression is also intrinsically linked to exploration.

Everyone and their mums are packin’ round here
Beyond a few starting skills and crafting recipes, all mechanical progression in Atomfall is unlocked through discovery. Manuals and training stimulants allow you to unlock new skills while crafting recipes provide throwables, consumables, and weapon upgrades. There is no experience bar, no levelling up, and no stat increase across the entire playthrough. This serves to focus you once again on the investigation.
If curiosity is the nucleus of Atomfall, combat serves as the orbiting electron. Between reading documents, chasing leads, and delving into the secrets hidden within the zone, you need to be aware of the dangers around every corner.
Atomfall combat is scrappy. With only one upgrade for increasing maximum health, enemies maintain a consistent threat level. As a regular person, it isn’t shocking that a few stray bullets will easily put you down, so when fighting other humans crowd control becomes the focus. Luckily your enemies are just as weak to a lead diet.
You’ll often find yourself ducking behind cover to craft a Molotov cocktail or bandage in the heat of the moment, as bullets continue to whizz by. While I initially hoarded my explosives, Atomfall’s limited inventory size encourages you to use them frequently to thin large groups or deal massive damage. This becomes especially important against tougher enemies where it is wise to keep your distance or risk a swift death.

While there aren’t any hunger bars to manage, you will need to scavenge for crafting resources. The balance is precise enough that this is present but never overbearing. Unless you’re extremely reckless, you’ll always have enough resources to continue your investigation.
Enemy variety is, however, a weaker element of Atomfall. Much of your time will be spent fighting the same human enemies, and while there are some more interesting and monstrous threats to contend with, their appearances are limited to select areas. I wish Atomfall had done more to differentiate the combat against the various human factions, as currently fights against each feel very similar. Out of all the encounters, my fights against B.A.R.D robots and feral mutants were far more memorable than the more generic human enemies.
“Unless you’re extremely reckless, you’ll always have enough resources to continue your investigation.”
Mechanically, the combat is workman, providing exactly what it needs to without distracting from the primary pull of the investigation. Sadly, stealth fairs slightly less favourably, with a quite limited sandbox at your disposal. While bows provide a silent ranged takedown, and tall grass obscures you from enemies, I never felt as if stealth was a full option beyond delaying a louder engagement. Without basic tools such as a whistle, or thrown rocks to lure enemies out of position, stealth is not a reliable tactic for the majority of encounters. There are also very few non-lethal weapons, and I often left carnage in my wake.
While not a graphical showcase, Atomfall has a fantastic visual design. The rolling green hills are distinctive and the retro-futurism 1960s technology gives it a unique flair. Stunning vistas dot the countryside, to say nothing of what lies beneath the surface.
Atomfall is not a character-driven story, but I enjoyed the differing perspectives and morals personified by the relatively small cast. Despite some questionable facial animations, voice acting is strong across the board. The sound design overall is also standout, with punchy gunshots, skin-crawling whispers, and satisfying pings from the metal detector.

Survivor Bias
I’d like to commend Atomfall’s options and accessibility menu. In both difficulty and accessibility menus you will find countless options to tailor your experience in the zone. The granularity of the available changes is truly impressive. When I found myself easily escaping enemies after initiating combat, I adjusted their persistence.
Suddenly escaping an ill-thought-out approach was more difficult, forcing me to be more deliberate in initiating combat without adjusting enemy aggression or my survivability. In the accessibility menu, there are options to assist you in aiming, keeping track of enemies, discarding half-used clips of ammo, or even guidance on your investigation. These options mean Atomfall welcomes players of all skill levels and needs. If you’re curious if Atomfall will be accessible to you, all the available options are also helpfully documented online.
“…Rebellion has developed an immersive and surprisingly full setting in Atomfall…”
Technically Atomfall had very few, and minor issues. Once a portion of dialogue played out of order, and there were occasional graphical hiccups, but overall Atomfall was very stable and no major bugs occurred in my time with the game. I will note that moving over uneven terrain caused some strange mantling animations, which was odd but not game-breaking.
More than anything, I am fascinated to hear how other people piece together the events of the Windscale disaster and the fallout that follows. The mystery is tantalizing, and each discovery contextualises and recontextualises the characters you find in the zone. The process of finally deciding who to trust is truly a highlight.
Ultimately, Atomfall will provide you with answers if you’re thorough in your investigation, but not all of them. While I was hoping for a resolution to certain dangling threads, some are left for future instalments in this world. Thankfully, Rebellion has developed an immersive and surprisingly full setting in Atomfall, and I am already eager for the confirmed story DLC to unearth even more answers.

Great expectations
Finally, I think Atomfall deserves a discussion on genre and expectations. According to Rebellion, this is a survival-action game. According to the internet, Atomfall’s most relevant contemporary is Fallout. During my preview, I said Atomfall felt more like a light immersive sim, and I still firmly agree with that prior assessment.
“…Atomfall skews somewhere closer to BioShock.”
So, in my opinion, Atomfall skews somewhere closer to BioShock. There is a beautifully realised interconnected world, a variety of ways to approach particular problems, and a story set in a closed ecosystem after a disaster. Most importantly, there is a focus on environmental storytelling and collecting snippets of narrative to piece together a whole.
In the ways that BioShock felt like a stripped-back version of the immersive sim, Atomfall does as well. It doesn’t give you the full suite of verbs necessary to truly rise to be part of the genre, but in many ways, it feels inspired by and indebted to it. For me, this became a double-edged sword. Atomfall’s strengths are when it wears these inspirations proudly, and the minor weaknesses are when it doesn’t rise to its promise fully.
But, in the same way that we forgave BioShock for not being as complex as other immersive sims, I forgave Atomfall. When you’re piecing together documents from the B.A.R.D bunkers, discovering the secrets of the Casterfell druids, or exploring The Interchange – all of that fades away. The mystery is too tantalizing to not become engrossed in, and the world is too dense not to explore, investigate, and understand.
8.5
Great
Positive:
- The central mystery is compelling
- Leads are a narrative and mechanical success story
- Narrative design focuses on player freedom and curiosity
- Combat is satisfying if simplistic
- Accessibility is thoughtful and expansive
Negative:
- Enemy variety is less than stellar
- Limited stealth and non-lethal options
- Broader approaches would have been nice to see
Atomfall is a departure and a triumph for Rebellion Developments. A showcase of narrative freedom that allows players to discover their own story within a tightly designed puzzle sandbox. While the strict mechanics have been seen before, the depth of the world and strength of the central mystery are the secrets behind Atomfall’s true success.
