Creating a Metal Farm in Subnautica 2: A Step-by-Step Guide

Building a Metal Farm in Subnautica 2 is incredibly beneficial for duplicating rare metals like Troilite. As you progress and work on repairing the Alien Power Plant, you’ll find that this material is scarce on the map, making a Metal Farm a far more efficient solution.

To get started, you need to have accessed the Alien Ruins area through the Tadpole Pens and equipped the Tadpole Depth module. Here’s how to unlock the Metal Farm blueprint and how it operates.

You’ll need to scan three Metal Farms to unlock the blueprint. Fortunately, they’re all located in the glowing green pool area about 870 meters northeast of the Alien Ruins Research base, roughly at a bearing of 75 degrees. This spot is quite deep, around 450 meters, which is the maximum depth your Tadpole can reach with the depth module.

Be cautious, as this area is teeming with predators and is monitored by a leviathan. Bring a Repair Tool for your Tadpole and some healing items for yourself. If you need guidance on how to navigate there, a video can help, but here’s a quick rundown:

Scan a few Metal Farms while keeping a low profile to avoid the leviathan. While you’re in the area, don’t forget to collect some Troilite and an Axum Bacterial Culture by breaking materials in the pools, as you’ll need both to craft the facility.

Metal Farms have a unique aspect: they require power, but their blueprint doesn’t specify power consumption. You’ll likely need to set up additional power infrastructure to support them. Since you can place them anywhere, it’s wise to build one near your existing power sources to avoid the hassle of creating an extra transmitter.

Crafting a Metal Farm requires:

To craft a Mangalloy Ingot, you’ll need one Troilite, one Atacamite, and one Titanium Ingot.

Once you have power, using the Metal Farm is pretty straightforward:

When you smash a node, you’ll receive a random amount of ore—anywhere from one to three. After that, the Metal Farm will begin producing more. If you can establish the necessary power infrastructure, you can even create multiple Metal Farms to maximize your ore production.
