Infrastructure 1

Lore & Background

The world the player wakes up on is quiet in a way that feels deliberate. No cities. No roads. No hum of machinery. Just iron ore scattered in rust-colored patches, copper glinting in the dirt, and the distant, patient threat of spitters and biters. The first act of defiance against that silence is a furnace. You build it from stone. You feed it coal and iron. And for the first time, something *makes* something else. The click of a furnace finishing a smelt is, for many players, the sound the game truly begins. Infrastructure 1 is not a single technology so much as a *phase*—the era where the player's hands are still doing a lot of the work that machines will eventually take over. You place belts by hand. You position inserters one by one, watching them clunk and grab. You run power cables between poles, praying the network doesn't flicker. It is tedious, it is beautiful, and it is the only way to learn the language of the factory before you start speaking it fluently. Fans often describe this era as the game's true tutorial, even though no tutorial exists. The world teaches you through constraint: limited resources, no automation yet, and the ever-present knowledge that a biter swarm is three minutes away from your little stone-furnace village. Infrastructure 1 is where the player stops being a survivor and starts being an engineer.

In Their Own Story

The sun was low and orange, bleeding across the flat grass. Mara crouched by the iron patch, her fingers black with ore dust, and counted the pieces she'd pried loose: eleven. Twelve. Not enough for the furnace. Not enough for anything. She stood, wiped her hands on her overalls, and looked at the stone she'd hauled from the riverbed an hour ago. Twelve blocks. Enough for one furnace. One. A single, squat, grey box that would turn iron into something *useful* if you fed it coal and waited. She placed it. The little progress bar appeared. She fed it coal. She fed it iron. And then she sat on a rock and watched, because there was nothing else to do, and because the waiting felt like a prayer. When the door opened and the iron plate slid out, she picked it up. It was warm. It was *hers*. Somewhere to the east, a biter hissed. She ignored it. She had a belt to lay.

Reader's Guide

Infrastructure 1 sits at the very root of Factorio's tech tree. It is the first cluster of technologies a player researches after assembling the initial science pack, and it unlocks the basic building blocks of every factory: the standard transport belt, the standard inserter, the stone furnace, and the earliest power-generation options (coal-powered generators and, soon after, the first electric infrastructure). Because it has no prerequisites beyond the starting science pack, it is always the first thing on the research queue. Once complete, it opens the door to every subsequent tier—Logistics 2, Inserter 2, Transport Belt 2, Furnace 2, and so on. Skipping it is not an option; the game literally will not let you build fast belts without first building basic belts. In terms of save and share mechanics, Infrastructure 1 is not a blueprint in the traditional sense. Blueprints in Factorio are *layouts* of placed items that you copy, save to a clipboard, or paste into your save. You cannot "blueprint" a technology. However, the *results* of Infrastructure 1—your first belt lines, your first furnace rows, your first power grid—are the very things players most often blueprint and share in the early game. Community "starter factory" blueprints are essentially Infrastructure 1 made portable: a compact arrangement of belts, inserters, and furnaces that a new player can paste down and immediately begin producing iron plates, copper plates, and steel. The interaction with the tech tree is strictly linear at this stage: Infrastructure 1 → tier 2 technologies → tier 3, and so on. There is no branching yet. The tree is a single trunk, and Infrastructure 1 is the root.

Did You Know?

• The first few minutes of a new Factorio save are entirely manual: no belts, no inserters, no furnaces. The player literally hand-carries iron ore to a crafting menu. Infrastructure 1 is the technology that ends that era.
• The stone furnace unlocked in this tier is the only furnace that uses no fuel type other than coal, oil, or wood—making it the sole smelting option until the player has access to steel and electricity.
• Many speedrun and challenge-community players refer to the period before Infrastructure 1 is researched as 'the hand phase,' a term that has become a lighthearted in-joke about the game's deliberately slow start.
• The basic transport belt unlocked here moves items at a rate of one item per second, a baseline that every later belt tier (fast, express) is measured against in the community's production-math culture.
