Troilite in Subnautica 2 | How to Get
Troilite is one of the rarest and most crucial resources in Subnautica 2, essential for crafting Mangalloy Ingots and progressing through the game's story. Unlike other materials such as Atacamite, Troilite is found in extremely limited quantities in a specific deep-sea location, making it a resource you need to manage carefully. Many players have accidentally soft-locked their progress by using all their Troilite without saving any for Metal Farms, so understanding how to find and manage this resource is vital for your survival journey.
What is Troilite Used For in Subnautica 2
Where to Find Troilite in Subnautica 2
Troilite can be found in the glowing green pool area surrounded by Metal Farms, located to the northeast of the Alien Ruins Research Base. The location bears approximately 75 degrees on the compass and sits about 870 to 1,000 meters from the alien observatory. This area is an old industrial plant that was historically used for mining metals from the ground, and the Troilite appears within clumps of Mineralized Clinker, which look like mounds of industrial runoff or green algae stuck to rocks.
The depth of this location reaches around 450 meters, which is the absolute threshold for your Tadpole submarine even with the Depth Module equipped. This means you will likely need to leave your Tadpole at its maximum depth and swim further down to reach some of the Troilite nodes. Make sure you have adequate oxygen supply before venturing out of your vehicle.
How to Reach the Troilite Location
To reach the Troilite location, start from the Alien Ruins Research Base and head east. Drop off the edge and descend until you spot a large purple tube, then follow it towards the Angel Comb beneath the Alien Power Plant. From the Angel Comb, continue northeast following another purple tube down a ravine until you reach the area with green-glowing pools and pillar-like alien structures arranged around the outside. These pillars are the Metal Farms.
An important navigation tip is to go right from the observatory to avoid the Leviathan that patrols the area to the east. The path is relatively straightforward once you know the landmarks, but the depth and hostile creatures make it a dangerous journey regardless of your route choice.
Dangers and Preparation
The area where Troilite is found is patrolled by a Leviathan and several other aggressive predators, making preparation essential before you embark on this expedition. You should bring a Repair Tool for your Tadpole, as it will likely take damage during the journey. Healing items and a full oxygen supply are also critical since you will need to exit your vehicle at extreme depth.
Your Tadpole must have the Depth Module installed as an absolute prerequisite, as the location exceeds normal diving depths. Additionally, bring your Sonic Resonator, which is the tool required to mine the Mineralized Clinker nodes and extract the Troilite from them. Without this tool, you will not be able to harvest the resource even if you find it.
How to Mine Troilite
Once you arrive at the glowing green area, look for green mineral formations scattered around the location. These are the Mineralized Clinker nodes that contain Troilite. Use your Sonic Resonator to break them down and collect the Troilite inside. The nodes are scattered throughout the area, so take time to scan and locate every available deposit before your oxygen runs low.
Before you begin mining, prioritize scanning the entire area first. This allows you to identify all available nodes and plan your collection route efficiently. The green minerals are relatively easy to spot against the darker ocean floor, but they can be hidden behind structures or tucked into crevices, so thorough exploration is recommended.
Critical Tip: Save at Least One Troilite for Metal Farms
This is the most important piece of advice regarding Troilite in Subnautica 2: always keep at least one Troilite in reserve for use in a Metal Farm. Metal Farms are devices that can produce a metal of your choice indefinitely, but they require you to insert one unit of that metal first to begin production. If you process all your Troilite into Mangalloy Ingots without saving one for a Metal Farm, you may soft-lock your progress entirely.
Many players have reported being unable to continue the game after making this mistake, as it remains unclear whether Mineralized Clinker nodes respawn over time. The safest approach is to scan the Metal Farm blueprint from the pillar structures in the Troilite area, build a Metal Farm at your base, and insert one Troilite to begin farming more. This guarantees you will never run out of this precious resource regardless of how much you need later in the game.
Additional Items at the Troilite Location
While you are in the area collecting Troilite, take the opportunity to grab other valuable items available at this location. The Metal Farm blueprint can be obtained by scanning the pillar-like alien structures surrounding the green pools. The Feedback Resonator and the Axum Bacterial Culture are also found here and are worth picking up if you have inventory space and sufficient oxygen remaining. Since reaching this location is dangerous and time-consuming, maximizing each trip by collecting everything available is the smartest approach.
Summary
Troilite is a rare but essential resource in Subnautica 2 found deep in the glowing green pools northeast of the Alien Ruins Research Base. Reach it by following the purple tubes past the Angel Comb, bring your Depth Module-equipped Tadpole and Sonic Resonator, and always save at least one Troilite for your Metal Farm to ensure unlimited future production. With proper preparation and resource management, you can avoid the soft-lock trap and smoothly progress through the Alien Power Plant repair and beyond.
