IC2 Classic Mod — Reference

Core Mechanics: The EU System

The Energy Unit (EU) is the lifeblood of IC2 Classic. Understanding how it flows is critical to preventing your machines from exploding.

Voltage Tiers

Every machine has a maximum input voltage. Exceeding this will cause the machine to explode.

Cable Loss and Insulation

Energy is lost as it travels through cables. Better materials and insulation reduce this loss.

• Tin Cable: Best for LV. Very low loss over short distances.
• Copper Cable: Standard for LV/MV. Moderate loss.
• Gold Cable: Required for MV/HV. High loss unless insulated.
• HV Cable (Iron): Used for HV/EV. Massive loss over distance.
• Glass Fibre Cable: The gold standard. Extremely low loss and handles up to 512 EU/p (or more in specific configurations).

Resources and Ores

IC2 Classic introduces several new materials that are essential for crafting circuits, machines, and tools.

Natural Resources

• Copper Ore: Found at middle elevations. Used for basic wiring and small power storage.
• Tin Ore: Found at middle elevations. Used for tin cans, batteries, and bronze alloy.
• Uranium Ore: Rare, found deep underground. The primary fuel for Nuclear Reactors.
• Lead Ore: Used for radiation shielding and advanced batteries.
• Rubber Trees: These trees feature distinctive orange 'sticky resin' spots. Use a Treetap on these spots to collect resin, which is smelted or extracted into Rubber for insulating cables.

Alloys and Processed Materials

• Bronze: Created by mixing 3 Copper Dust and 1 Tin Dust. It is as strong as Iron but more durable.
• Refined Iron (Steel): Created by smelting Iron Ingots a second time (in 1.12.2) or via the Blast Furnace. Essential for machine casings.
• Carbon Plate: Made from Raw Carbon Mesh compressed in a Compressor. Used for high-end armor and machines.

Processing Machinery

Automation begins with processing raw materials into more efficient forms.

The Core Trio

1. Macerator: Grinds ores into 2 Dusts, effectively doubling your ore yield. It can also grind gravel into flint or bone into bone meal.
2. Electric Furnace: A faster, EU-powered version of the vanilla furnace.
3. Extractor: Processes Sticky Resin into 3 Rubber (compared to 1 in a furnace). Also used to create Coils and Fuel.

Advanced Processing

• Compressor: Turns loose materials into dense plates. Essential for creating Carbon Plates and Advanced Alloy.
• Recycler: Consumes any item to produce 'Scrap'. Scrap can be used to create Scrap Boxes or as a catalyst in a Mass Fabricator.
• Mass Fabricator: Consumes massive amounts of EU to produce UU-Matter, a liquid or solid that can be crafted into almost any resource in the game.
• Induction Furnace: An advanced furnace that processes two stacks at once and becomes faster as it stays hot.

Tools and Equipment

IC2 Classic replaces the need for disposable tools with rechargeable electric versions.

Electric Tools

• Mining Drill: Equivalent to an Iron Pickaxe/Shovel. Can be upgraded to a Diamond Drill.
• Chainsaw: A powerful axe and shears combo. Highly effective against leaves and wood.
• Electric Treetap: Quickly harvests resin without the manual clicking.
• Nano Saber: A high-tech sword that deals massive damage when turned on, consuming EU per hit.

Armor Sets

• Hazmat Suit: Protects the player from radiation (essential for handling Uranium) and fire damage.
• Nano Suit: High-tier armor that provides significant damage reduction using EU.
• Quantum Suit: The pinnacle of technology. It makes the player nearly invincible, allows for super-speed, massive jumps, and underwater breathing. It requires a Mass Fabricator to produce the necessary materials.
