Belts of Iron is an intense factory automation simulator that puts you in charge of a struggling manufacturing plant. You play as a former factory worker who was laid off when the old owners went bankrupt. You scraped together your savings, bought the abandoned factory at auction, and now you are the boss. The machines are rusty. The conveyors are broken. The employees are skeptical. But you see potential. You know you can turn this place around. One belt at a time.
The story begins at the factory gate. The security booth is empty. The parking lot is overgrown. You unlock the main door. The smell of oil and dust hits you. Machines stand silent. Conveyor belts sit motionless. A single light flickers overhead. You walk to the office. The desk is covered in old paperwork. You find a sticky note on the monitor. “We tried everything. Good luck.” You crumple the note. You turn on the power. The factory hums to life. Time to work.
The core gameplay focuses on designing conveyor belt systems, managing resources, and optimizing production. You start with basic machines — a furnace for smelting ore, a press for shaping metal, a grinder for smoothing edges, and an assembler for putting parts together. Raw materials come in on one side. Finished products go out on the other. Your job is to connect them with conveyor belts.
Conveyor belts are your lifeline. Straight belts move items quickly. Curved belts change direction. Splitter belts divide items into multiple paths. Merger belts combine items from multiple paths. Elevator belts move items up and down. You have to plan your layout carefully. A poorly designed belt system creates bottlenecks. Bottlenecks slow production. Slow production loses money.
You can upgrade your machines. Better furnaces smelt faster. Better presses shape more precisely. Better grinders smooth more efficiently. Better assemblers build more reliably. Each upgrade requires resources and research. You have to balance spending on upgrades versus saving for new machines.
The game has a research tree. Unlock new belt types, new machines, and new efficiency upgrades. Research requires science packs — which you have to produce on your own belts. The more you automate, the faster you research. The faster you research, the more you automate. The loop is satisfying and addictive.
You hire employees. Each employee has skills — speed, accuracy, and stamina. Faster employees work quicker. More accurate employees make fewer mistakes. Higher stamina employees work longer shifts. You can train employees to improve their skills. You can also fire underperformers. Managing your workforce is as important as managing your belts.
The game has a day-night cycle. Day shifts are productive but expensive — wages are higher. Night shifts are cheaper but slower — employees are tired. You have to balance cost and output.

Graphics and Sound
Visually, Belts of Iron is industrial and detailed. The factory is dark and gritty — rusted machines, oil-stained floors, flickering lights. The conveyor belts are animated — items move smoothly from machine to machine. The machines have moving parts — pistons pumping, gears turning, sparks flying. The employees are small but expressive — they walk faster when stressed, slower when tired, and cheer when a bottleneck is fixed. The HUD shows production rates, resource levels, and efficiency percentages. The camera can zoom from a bird’s-eye view of the entire factory to a close-up of a single belt.
Audio is mechanical and satisfying. The soundtrack features industrial rock and electronic beats. The sound effects are crisp — the hum of a furnace, the clank of a press, the whir of a grinder, the click of an assembler, the rumble of conveyor belts. Employees have voice lines — calling out problems, celebrating successes, complaining about night shifts. Alarms sound when a machine breaks or a belt jams. The sound of a perfectly optimized factory is the sound of steady, rhythmic production.
Why You Should Play Belts of Iron
If you enjoy factory automation games, resource management, or optimization puzzles, this is for you. The 10 GB install size is reasonable. A full playthrough from startup to fully automated factory takes 15 to 20 hours. Optimizing every belt and unlocking every upgrade can take 25 to 30 hours.
The game is addictive. The loop of building, observing, and optimizing is deeply satisfying. The research tree gives you long-term goals. The employee management adds a human element. For completionists, there are achievements for producing a million items, for running a factory with no bottlenecks for 24 hours, and for unlocking every research upgrade.
Final Verdict on Belts of Iron
Belts of Iron is a solid, satisfying factory automation simulator that captures the addictive loop of games like Factorio and Satisfactory. The belt system is deep, the upgrades are rewarding, and the employee management adds a unique twist. If you enjoyed games like Shapez, Factory Town, or Production Line, this title belongs in your library.
The fully unlocked version from Koyso gives you access to the complete game — all machines, all belts, and all upgrades — immediately. No grinding. No microtransactions. Just 10 GB of industrial optimization.
