Krastorio 2 — Field Codex

Comprehensive industrial reference compiled directly from Lua prototype definitions.

Factorio 2.0 Ready Complete Tech Trees

Krastorio 2 is an overhaul that preserves vanilla Factorio's core shape while dramatically extending its mid and late game. Originally created by Krastor and Linver, maintained by raiguard. It introduces new mineral tiers, 40+ specialized production buildings, 120+ technologies, rebalanced combat mechanics, and a standalone galactic victory condition.

The five things that will trip you up

• Science packs are tech cards, and they have strict lab tiers. Each tier requires a dedicated laboratory building. Early cards are phased out of research costs as you climb, so older science lines get retired rather than expanded forever.
• Production and utility cards are made in the Research Server. They cannot be built in assembling machines. You must construct the server before you can craft the cards it accepts.
• Wood is a critical industrial input, not decorative scenery. Electronic circuits, coke, and air purification filters all consume wood continuously. Greenhouses are early and mandatory.
• Stone is a rich processing tree, not a dead end. Stone crushes into sand, sand smelts into glass or filters into quartz, and quartz smelts into high-purity silicon for electronics.
• The crusher voids surplus. Most items fed into the crusher are destroyed outright; only specific recipes yield components. It is the mod's intended tool for clearing loop bottlenecks and fluid overflow.

Nine progressive steps from spaceship crash survivor to a self-sustaining matter civilization. Research ordering is strictly tiered — each tier gates access to the next generation of materials and machines.

Three new world resources spawn naturally on the map alongside the standard vanilla resources.

New Metals & Resources: Rare Metals, Raw Imersite, and Mineral Water springs. 🔍 Click to enlarge

Imersite

Rare, late-game, and unusable in raw form. Raw imersite must be mined with a heavy Quarry Drill (standard electric drills cannot mine it). Crushing raw imersite yields imersite powder and byproduct sand. Combining powder with rare metals forms Imersium — the structural alloy of the endgame.

Rare metals

Combines the industrial roles of titanium, platinum, and gold. Smelts directly into rare metal plates, which feed processing units, imersium alloys, AI cores, and matter research data. In K2, processing units consume rare metals rather than complex circuit chains.

Mineral water

A surface liquid resource extracted via standard pumpjacks. Essential for lithium chemistry: mineral water yields lithium chloride, which electrolyzes into metallic lithium and chlorine gas for advanced energy storage.

Stone, sand, quartz

Crush stone into sand. Sand smelts directly into glass, or washes through water filtration into quartz crystals, which smelt into pure silicon.

Coal and coke

Coke is produced from coal and wood. It replaces raw coal in high-yield steel smelting (10 iron plates + 2 coke = 5 steel) and provides a cleaner, higher-energy fuel source.

Advanced chemical enrichment multiplies raw ore yield, while advanced assemblers can forge raw materials directly into finished components.

Crusher Mechanics: Ore pulverization, byproduct separation, and surplus voiding. 🔍 Click to enlarge

Enriched ores

Treating 9 raw ore with sulfuric acid and water in a chemical plant yields 6 enriched ore. 5 enriched ore smelt into 5 full plates — representing a massive 20% gain in material efficiency. The byproduct dirty water is filtered back into clean water and recovered mineral byproducts in a closed loop.

Smelting-crafting

Advanced assembling machines can execute direct smelting-crafting: turning raw or enriched ores directly into gears, sticks, and beams in one step, bypassing intermediate plate bottlenecks.

Advanced machine tier

Unlocked by the Advanced Tech Card. Each advanced machine provides substantial speed increases and accommodates 4 module slots.

K2 introduces 12 specialized fluids and 4 dedicated processing facilities for atmospheric condensation, water electrolysis, and byproduct filtration.

Filtration plant

Cleans dirty industrial wastewater back into pure water while recovering stone, iron, and copper traces. Also purifies heavy oil into solid coal and filters sand into quartz.

Electrolysis plant

Splits pure water into oxygen and hydrogen gases, separates saline sand into chlorine and hydrogen, and refines heavy water for nuclear fusion.

Atmospheric condenser

Extracts atmospheric gases using purely electricity. Never runs dry. Gathers oxygen, nitrogen, hydrogen, and atmospheric humidity.

Fluid Directory

Fuel Progression: Raw wood & coal → Coke → Solid Fuel → Biofuel → Advanced Fuel. 🔍 Click to enlarge

Greenhouse

Cultivates timber using water and electricity. Adding nitrogen fertilizer doubles yield per cycle, providing the high wood volume demanded by electronic circuits and steel coke.

Biomass & Bio Lab

Destroying alien biter nests drops raw biomass. The Bio Lab cultivates additional biomass using petroleum gas and oxygen. Biomass is synthesized into biter research data, medical kits, and organic catalysts.

Fuel hierarchy

A graded fuel ladder. Standard fuel is refined from light oil or solid fuel with hydrogen; biofuel and imersite-infused advanced fuel offer premium vehicle speed and acceleration bonuses.

Three specialized laboratory buildings consume distinct bands of science tech cards.

Lab Acceptance Matrix

Laboratory	Accepted Tech Cards	Power Draw	Base Speed

Where cards are computed

The signature late-game system. The Matter Plant dissolves solid materials into liquid matter fluid, while the Matter Associator condenses matter fluid into desired target items. An asymmetric exchange rate prevents infinite free resource duplication.

Intergalactic transceiver

The alternate win condition. Requires monumental quantities of imersium beams, rare metals, energy control units, and 300 AI cores. Once erected, it draws enormous continuous electrical power to charge its trans-dimensional array until it transmits and secures victory.
