From Press Release:
UNITED STATES, May 4, 2026 – Indie developer, Builderment LLC has announced its latest factory automation game Belts of Iron will launch into Steam Early Access on May 28th. Belts of Iron literally drops you into a vast procedurally generated world where survival quickly turns into an obsession for optimizing your factory. Design massive production lines, build power and rail networks that go for miles, and fight hostile enemies to obtain the valuable resource they protect. All in pursuit of building a rocket capable of taking you home, or stay if you feel like you’ve made a nice home by then.
Since Belts of Iron was announced last fall the developer has been constantly updating and improving the game, sharing progress through regular dev logs and the growing discord community. The demo has been played by thousands of players on Steam and covered by popular gaming YouTube creators such as Orbital Potato and Z1 Gaming.
About the game
Belts of Iron is an open world factory automation game where belts are just the beginning. After crash-landing on an alien planet you start mining ore and smelting ingots to craft belts and basic machinery. Soon you have a small factory producing data packs that can research new technology. It’s not much but it’s yours and it works, for now. New research unlocks oil refineries and fluid mechanics. Suddenly you’re weaving pipes full of crude oil, petroleum, and water throughout your neatly placed rows of belts. Your machines start to hunger for more power, so you scale up electricity generation with massive steam turbines. You feel like you’ve got it all figured out just as your initial resource deposits begin to dry up. And then you hear the low rumble of iron horses coming to save you. Choo choo! Freight cars hauling wagons full of valuable resources over miles of railway tracks back to the factory. Only you’re not alone, and the native creatures do not like what you’re doing to their home. Luckily this isn’t your first rodeo and you’ve come prepared, didn’t you? Now that you’ve made your presence known and your factory is humming at 100% efficiency, it’s time to build a rocket and go home. Or don’t. The factory could always be bigger.
Key Features
