Quick answer
Current Troilite reporting points players toward the deep late-game region northeast of the Alien Ruins Research Base, in a green-pool area connected to Metal Farms. Save at least one Troilite for Metal Farm duplication and one more if Entangled Power Cell is your next power craft before converting the rest into Mangalloy Ingots.
Troilite route notes
Do not treat Troilite like a casual early resource
Current reporting places Troilite in a dangerous late-route area near the Alien Ruins Research Base, so prepare the Tadpole, oxygen, healing, and repair supplies first.
Use the Alien Ruins Research Base as the anchor
PC Gamer reports the route as northeast of the Alien Ruins Research Base, toward a deep green-pool area associated with Metal Farms.
Watch your depth and return plan
Reported route depth reaches roughly the limit of an upgraded Tadpole, so this should be planned like an expedition rather than a quick material run.
Scan and mark what you can
If you reach the Metal Farm area, prioritize scanning valuable structures and noting the route. The best guide value comes from repeatability.
Keep the Entangled Power Cell route separate
Entangled Power Cell currently lists Troilite alongside Conduit Crystal, Strong Acid, and Gold Ingot. Save one tagged Troilite before converting the rest into Mangalloy.
Why Troilite is risky to waste
| Risk | Planning note |
|---|---|
| Depth pressure | The reported route goes very deep and may require upgraded vehicle planning. |
| Predators | PC Gamer notes predators and a leviathan threat around the route, so repair and healing supplies matter. |
| Resource scarcity | Launch-week reports describe Troilite as rare enough that careless crafting can hurt progression. |
| Power crafting | Entangled Power Cell planning can compete with Mangalloy and Metal Farm use. |
| Patch drift | Unknown Worlds added more Troilite resource areas in Hotfix 2, so older scarcity notes may need rechecking. |
Metal Farm rule
The safest current advice is simple: keep one Troilite before crafting aggressively. PC Gamer reports that Metal Farms can duplicate a metal only after you insert one of that metal first, which makes one saved Troilite more valuable than one rushed Mangalloy craft. If Entangled Power Cell is already unlocked, tag a second Troilite for that recipe too.
FAQ
Where do you find Troilite in Subnautica 2?
Current reporting points toward the deep late-route region northeast of the Alien Ruins Research Base, near green-pool and Metal Farm routes. Treat exact coordinates as patch-sensitive.
What is Troilite used for?
Troilite is tied to Mangalloy planning, Metal Farm duplication setup, and the Entangled Power Cell recipe in current public data.
Should you turn Troilite into Mangalloy right away?
Usually no. Keep at least one Troilite for Metal Farm use, and keep another if Entangled Power Cell is part of your next power route.
Did Hotfix 2 change Troilite?
Unknown Worlds said Hotfix 2 added more Troilite resource areas in the late-game region, so launch-week scarcity notes should be rechecked after patches.

- Recheck this page after every resource-flow patch or major Early Access update.
Field notes
Spend the first sample on information
Before crafting, use the first successful Troilite run to confirm the route, mark the return path, and decide whether Metal Farm or Entangled Power Cell matters more.
Old scarcity advice needs a date
Hotfix 2 added more late-game Troilite resource areas. If a guide says there is only one tight source, check whether it was retested after May 28, 2026.
Do not run the route tired
Troilite sits in the kind of route where small mistakes stack up: depth, predators, power, and panic. Bank partial progress instead of forcing one heroic dive.
Hotfix 2 changed the resource picture
Unknown Worlds added more Troilite resource areas in the late-game region in Hotfix 2. That is good for players, but it also means old launch-week scarcity wording should be treated as patch-sensitive rather than permanent.
