The Atomfall map is split up into several key areas you’ll backtrack through. It’s a dense, detailed world, and well worth exploring. But if you want to know how big the map is and what it holds, we’ve got answers.
An RPG’s map size is an unavoidable question at this point. I’d say the sandbox stylings of GTA kickstarted the topic many years ago. Ubisoft popularized the construction of gigantic maps, and now it’s commonplace. We have reached a point where maps are getting too big, and it’s nice when an RPG cuts back on the square-feet of land.
Atomfall promises an adventure through an alternate-history Cumbria. The area is quite a decent part of England, but has Rebellion brought Cumbria to life, to scale?
Is Atomfall Open World?

Atomfall is not a bona fide open-world title and is akin to a semi-open-world title featuring several interconnected biomes.
The best way to describe Atomfall‘s map is like Borderlands. It has a ton of large-scale areas, but you need to go through a loading screen to get to them, so it’s not a completely open world. I prefer this kind of map in many ways as it allows the developer to concentrate their efforts on creating unique, focused biomes.
How Big is Atomfall’s Map? All Areas Explained
Collectively, Atomfall’s map is comparable to a medium-sized open world game and consists of six large areas.
Atomfall is made up of six main biomes:
- Casterfell Woods
- The Interchange
- Sewer Tunnels
- Slatten Dale
- Skethermoor
- Wyndham Village
Outside of The Interchange and Sewer Tunnels, the remaining four areas are all outdoors. They feature an assortment of POIs, NPCs, enemies, hidden bunkers and underground areas, and mines. To explore one of the biomes inside out, you’re looking at several hours each, quite easily.
The Interchange is the basis of the story, whereas the Sewer Tunnels are an efficient way of getting from area to area.
