How to Build a Metal Farm in Subnautica 2: A 2026 Guide

Building a Metal Farm in Subnautica 2, developed by Unknown Worlds, is a highly efficient method for duplicating rare materials like Troilite. As players progress toward repairing the Alien Power Plant, the demand for these rare resources increases significantly, making the construction of a dedicated farm a logical step for resource management on PC. To successfully establish your own facility, follow these initial steps:

1. Reach the Alien Ruins area via the Tadpole Pens.
2. Equip the Tadpole Depth module to your vehicle to survive the 450-meter depth.
3. Travel 870 meters northeast of the Alien Ruins Research base to the glowing green pools.
4. Scan three Metal Farm structures to unlock the blueprint.
5. Gather Troilite and Axum Bacterial Culture from the pools.
6. Construct the Metal Farm near an existing power source.

Locating Metal Farm Blueprints

To acquire the Metal Farm blueprint, you must scan three individual Metal Farm structures. These are located in a specific biome characterized by glowing green pools, situated approximately 870 meters northeast of the Alien Ruins Research base at a bearing of 75 degrees. The depth in this region reaches 450 meters, which is the maximum operational limit for the Tadpole vehicle even when equipped with the necessary depth module. Players should prepare for hostile encounters, as the area is patrolled by a leviathan and various predators. We recommend bringing a Repair Tool for your vehicle and sufficient healing items for your character.

Navigation to the Blueprint Site

To reach the site, start from the Alien Ruins Research Base and head east. You will need to descend off the cliff until you encounter a purple tube. Follow this tube until you reach the Angel Comb. From the Angel Comb, continue northeast, following another purple tube down into a ravine. This path leads directly to the green glowing pools surrounded by alien column-like devices; these columns are the Metal Farms you need to scan.

Once you have scanned the required structures, you can construct the facility. While the blueprint does not explicitly list power consumption, the nature of the device requires a stable energy supply. It is recommended to build the farm near your existing power infrastructure to avoid the need for additional power transmitters. You can find more guides on our portal to help optimize your base layout.

Crafting Requirements

To craft the Metal Farm, you will need the following materials:

• 1x Mangalloy Ingot
• 1x Axum Bacterial Culture

The Mangalloy Ingot itself requires a specific recipe: one Troilite, one Atacamite, and one Titanium Ingot. Ensure you collect extra Troilite and Axum Bacterial Culture while you are at the blueprint location, as these are mandatory components for the construction process.

How to Use a Metal Farm

Operating the Metal Farm is a straightforward process once power is established. The primary function of the facility is to duplicate metals that you have already acquired. To begin, insert the desired metal into the storage interface of the farm. Once the internal timer completes its cycle, the device will produce a harvestable node on top of the structure. You can then use your tool to smash this node and collect the duplicated materials. This cycle can be repeated as long as the facility remains powered, providing a consistent supply of rare resources.

Frequently Asked Questions

How do you get Troilite in Subnautica 2?
