$35Factorio Build the machine that builds everything
Factorio starts with you chopping trees and mining ore by hand, and ends with solar fields, oil refineries, trains and robots running a factory the size of a city. For city builder fans, the appeal is the layout puzzle: belts, power and production lines that keep growing until the whole map hums.
Is Factorio worth it?
Factorio is worth it if…
- you like laying out production districts and watching them run on their own
- you enjoy solving bottlenecks in power, belts and train networks
- you want a long open-ended build you can expand or rebuild forever
- you like cooperative building where friends split planning and construction

From hand tools to a machine empire
You land with almost nothing and make the first plates yourself, chopping wood and feeding coal and ore into a furnace. Soon miners dig for you, belts carry ore to furnaces, and mechanical arms load machines without a click from you. Research opens solar fields, oil refining and cracking, plus construction and logistic robots. What began as a workbench becomes districts of smelters, refineries and assembly lines, all placed, powered and connected by you.
Planning streets of belts and rails
You lay out belts, sort inputs and outputs, balance power, and leave room for the next expansion that always arrives sooner than planned. Trains link distant mining outposts to the center, the way suburbs feed a downtown. You watch one bottleneck starve half the map, then redraw the whole junction. It is urban planning where the traffic never sleeps.
Pollution has neighbours
Heavy industry annoys the locals, a native bug-like species that attacks you and your buildings when pollution spreads. So alongside furnaces and labs you plan walls, gun turrets and supply lines for ammunition. Research and growth make you stronger, but a bigger factory makes a bigger target. You decide how far to push outward, when to fortify, and which outpost is worth defending. Peaceful building on one side of the map can sit beside a chew-marked wall on the other.
Build alone or share the shift
The core freeplay scenario is an open-ended build toward a rocket, on an infinite 2D world drawn in detailed pixel art. You can run it solo and tinker at your own pace, or join cooperative multiplayer and split the work, with one friend on rail lines while another untangles oil. Mods range from small helpers to full overhauls, plus extra scenarios and an in-game map editor for custom maps and scripts. There is always another layout to try.
What else should city builder fans know?
Is this a city builder with houses and population?
No. The growing settlement is your factory itself: miners, furnaces, labs, solar fields, refineries, robot networks and train stations. The city-builder overlap is in planning space, infrastructure and supply, not in running a town.
How does a run start and what is the goal?
You start by hand, gathering wood and ore and crafting early parts, then automate one step at a time. Research unlocks more complex production, from oil processing to robots. In freeplay the broad goal is building toward a rocket, but the map is open and you set the pace, expanding, rebuilding and optimising for as long as you like.
How do trains fit into the factory?
Trains carry bulk resources from far mines to your main works, letting the factory spread across the map like connected districts.
Can I play peacefully and just build?
Combat is part of the design because pollution draws attacks, so some defence planning comes with growth. You can shape the experience with maps, scenarios and settings, and multiplayer lets friends share defence duty. If you want zero threat at all, this may not be the calm sandbox you have in mind.
