How to Find Crude Oil and Refine Modern Polymers

Building high-tier weaponry requires natural resources that generate in specific biomes and underground layers. Before you can manufacture Automatic & Experimental era firearms, you need to mine new ores and set up a crude oil refinery.

Locating New Ores and Crude Oil

1. Mine underground to gather sulfur ore for gunpowder production and tungsten ore for heavy-duty weapon crafting.

2. Travel to desert biomes and search the terrain for desert tar sands, which contain accessible deposits of crude oil on land.

3. If you are far from a desert, sail into ocean biomes and look beneath the ocean floor to locate underwater crude oil reserves.

4. Collect the raw crude oil and transport it back to your main factory.

Operating the Fractional Distillation Tower

1. Construct a Fractional Distillation Tower in your industrial area to process raw oil.

2. Feed the crude oil into the tower so it separates into refined outputs.

3. Store the resulting diesel fuel for power or fuel needs, and gather the special modern polymers.

4. Bring those polymers to your gunsmithing stations to craft late-game automatic and experimental firearms.
