Ores and raw materials
Tin Ore
Tin is an inner-biome metal used to advance workbench crafting and unlock access to further tools and automation.
WHERE & HOW TO FARM
Tin Ore
Clay Caves, immediately beside the Undergrounds around the Core.
Before you go
- Pickaxe suitable for Clay terrain.
- Combat supplies for larvae and Cavelings.
- Furnace for Tin Bars.
- Map access to record the route and ore finds.
Farming steps
- Start from the Core and explore through the Undergrounds until Clay Blocks identify the Clay Caves.
- If you first enter Forgotten Ruins, return to the Core and mine in another direction to find the neighboring Clay Caves.
- Look for Tin deposits in the cave walls and mine them with your pickaxe.
- Collect the dropped ore and keep clear of larva clusters and floor hazards while continuing the search.
- Return to base when your inventory or health calls for it, following your mapped route.
- Smelt Tin Ore in a Furnace and collect Tin Bars.
- Use bars for the next workbench and planned equipment, retaining any amount still needed for station recipes.
- Tin does not require Titan victories or Great Wall access.
- Do not confuse the Larva Hive with the ordinary Clay Caves; the hive’s dense larvae and hazards make it a separate risk.
Repeat, collect and use
Vein gathering repeats in unexplored Clay Caves terrain, but mined deposits do not renew. Explore additional branches when nearby ore is depleted.
Common mistakes
- Searching beyond the Wall for Tin: begin in the inner-ring Clay Caves.
- Entering the Hive to find ordinary Tin: search Clay terrain first and avoid the dangerous sub-biome unless intended.
- Spending bars before station needs are checked: keep the workbench requirement in reserve.
When to stop or switch
Return to crafting once you have the Tin Bars for the next workbench and immediate gear; switch to Gold or Iron if those are your next recipe bottlenecks.
