Multiple outlets explain that troilite is a specific resource in Subnautica 2 used to craft important items. Polygon and PC Gamer both state that troilite is needed to produce Mangalloy Ingots, which are tied to additional progression systems in the game. Beyond ingots, PC Gamer adds that troilite is also required for the Photovoltaic Charger upgrade, indicating the material supports at least part of the game’s energy and equipment upgrades. Polygon focuses on troilite’s role in manufacturing, including its use within a metal farming context, while PC Gamer frames the material primarily around its crafting and upgrade applications.
Taken together, the reports agree that troilite is a material players must obtain to move forward with metal-related crafting and at least one electrical upgrade. The articles also provide guidance on where to find troilite in the game world and how to use it in the relevant crafting recipes, though they differ slightly in emphasis between industrial farming and specific upgrade destinations.
