The Material Finder is the fastest way to plan a farming run in Marathon. Browse loot by zone to see every item that drops in the Perimeter, Dire Marsh, or Outpost, or search by faction upgrade to get a exact material checklist for any upgrade tier across Arachne, CyberAcme, NuCaloric, Sekiguchi, Traxus, and MIDA. The By Material view lets you pick any salvage item and instantly see every zone it drops in, which factions need it, and in what quantities.

Marathon upgrade materials are found as salvage drops in specific zones. Some materials like Unstable Gel and Drone Resin are needed in large quantities across multiple factions, making them high-priority farming targets early in your progression. Others are faction-exclusive and only required for a single upgrade tree. Knowing what to pick up before you extract is the difference between an efficient run and a wasted one.

For the full faction upgrade trees including costs and capstone requirements, see the Faction Upgrades guide. For item descriptions and usage details, see the Item Codex.
