Factorio: A Beginner's Guide (2026)

What Is Factorio

Factorio is a cult classic automation game from Wube Software. You are an engineer who has crash-landed on an alien planet: mine resources, build factories, lay conveyor belts and railroads, and eventually assemble a rocket to fly back home. The local wildlife—the Bites—won’t take kindly to your industrial expansion and will attack your territory. The core mechanic is growth: a factory is never “finished”; it always needs to be expanded, and that’s the whole fun of it.

The First Few Hours: From Campfires to Conveyor Belts

• Dig by hand and set up drilling rigs on coal, iron, and copper veins—manual labor should come to an end quickly.
• Automate smelting—stone furnaces with coal on one conveyor belt and ore on the other: this is your first “production line.”
• Build a steam power plant—boilers and steam engines will provide electricity for electric drills and automated assembly machines.
• Don’t build a “spaghetti” layout—leave space between production areas; the factory will expand.
• Automate the basics—conveyors, manipulators, and cartridges should be produced on their own, without your intervention.

Science and Research

Progress comes through research packages—test tubes that “consume” labs. Each new color requires an increasingly complex production chain:

Tip: Build flask production facilities in batches, each with several assembly machines—a shortage of science slows everything down.

Factory layout: main bus

When the “spaghetti” layout stops scaling, switch to the main bus: parallel rows of conveyors carrying basic resources (iron, copper, steel, plastic, schematics), with production blocks branching off perpendicularly from them. Rules: Leave 2–4 empty lanes for the future; balance the conveyor belts with dividers; don’t skimp on space. Produce medium and red circuit boards centrally—they’re needed everywhere.

Defense and Biteers

Pollution from factories triggers attacks by Biteers—their nests absorb it and evolve. Survival strategy:

1. Research turrets and walls early on; place them in lines along the edge of the pollution.
2. Clear out nests inside the pollution cloud while the Biteers are still small.
3. Use lakes and cliffs as natural barriers—this reduces the perimeter of your defenses.
4. Later on—use laser turrets, flamethrowers, and artillery to take out nests from a distance.

Robots, Trains, and Late-Game Strategy

Logistics robots transport items between network chests—build robot ports and assign small-scale logistics tasks to them. Trains are the solution for distant veins: stations with loading and unloading facilities, signals on tracks and at junctions (otherwise, collisions will occur). In the late game, productivity and speed modules, nuclear power, and bucket excavators become available. The finale is the rocket silo: thousands of slabs, fuel, and low-orbit structures. Once the rocket launches, the real Factorio begins—optimizing the factory to produce thousands of research packs per minute.

Common Beginner Mistakes

• Building too tightly without leaving space—every redesign turns into tearing down half the base.
• Manually moving resources for hours on end—automate anything you do more than twice.
• Ignoring defense until the first major wave—Biteers evolve over time and due to pollution.
• One conveyor belt for all metal—calculate throughput: one yellow conveyor belt handles 15 items per second.

Conclusion

Factorio is a conveyor-belt meditation and an eternal engineering challenge: there’s always room for improvement. Automate the routine, build with a margin of safety, defend the perimeter—and one day, a rocket will take you home. The factory is growing!
