Factorio is a deep and engaging factory-building simulation that challenges you to transform a wild alien world into a high-tech industrial powerhouse. You begin by chopping trees, mining ores and manually crafting basic components like transport belts and inserters. As your operation grows, you’ll research advanced technologies, set up automated assembly lines, expand into massive solar farms, refine and crack oil, and deploy fleets of construction and logistic robots. All the while, the planet’s indigenous creatures grow increasingly hostile, forcing you to defend your factory perimeter with turrets, walls and tactical strategies.
