Resources
Wood, metal, cloth, plastic, and other recovered materials support crafting and train expansion. The metal chain runs from scraps to slag metal and then pure metal; branches, logs, and charcoal are covered separately as Eden Engine fuel.

How Resources Works
Updated October 8, 2026Resource loop
The crew leaves the train to scavenge settlements, wreckage, ruins, bunkers, strongholds, and dungeons, then brings recovered materials back to onboard stations. Resources support weapons, equipment, repair, expansion, storage, heat, and motion.
Aku Jauhiainen gives one concrete production example: metal scraps are processed into slag metal and then pure metal. He says wood and plastic follow similar refinement logic, but does not publish every intermediate name or ratio.
- Scavenge the frozen levels
- Return materials to the train
- Refine metal scraps → slag metal → pure metal
- Use comparable refining systems for wood and plastic
Documented material requirement
One current official Steam screenshot documents a complete pre-release material list for the pictured Bolt-Action Rifle. Read the rifle entry for the full recipe, stat panel, and stock options; this one screen should not be generalized to other guns or assumed final for Q4 2026 Early Access.

Closed Beta data boundary
The announced Closed Beta window ran through September 7 and allowed players to record sessions. A new resource card or station screen can support a build-specific entry when its capture date and context are visible. The launch announcement does not publish refining ratios, fuel duration, carrying weight, stack size, or current station construction costs, so those numbers are not inferred from old footage.

Archived Assembly Station construction
A 2025 official reveal frame preserves an older Assembly Station placement preview. Its dated material names and cost are retained on the Train Stations page as development history, not current building advice.

What is still unknown
Official coverage does not provide a complete resource table. Community Beta records now describe additional recipes and processing routes, but their build version and in-game behavior still need checking.

Materials appearing in community Beta records
The community Beta database now has named records beyond the official screenshots. The entries below are reported values, not independently checked balance data: the pages do not identify a build ID or provide a screenshot for every field. Check your in-game card before spending materials, and do not combine them with older official screenshot values.
Scrap Metal Plate and Scrap Metal Pipe appear as ingredients for the reported Pipe Rifle recipe. Cloth is linked to Bandages, while Felt and Thread appear in clothing recipes. These are useful names to check in the demo; their full recipe quantities stay with the relevant equipment entries.
- Scrap Metal Plate and Scrap Metal Pipe: reported weapon ingredients
- Cloth: reported Bandages ingredient
- Felt and Thread: reported clothing ingredients
- Schematics and machine parts: reported train research materials
