Resource farming: Steel Cable, Refined Carbon, Optic Lens, and Canister routes

Route selector

These four materials do not share one farming method. Identify the missing item, then choose the source class that actually produces it.

Before leaving, write down the required quantity and the route's stop condition. The goal is to solve the next craft, not to fill every slot with unrelated loot.

Steel Cable: Mine Crate route

The current Steel Cable page lists placed copies, Mine Crates, and a Blacksmith trade. The Mine Crate table is the strongest route anchor because every destroyed crate lists one Steel Cable at 100 percent. Secondary drops are chance-based and should not be included in the guaranteed route count.

Mine Crates appear in Manufacturing West, The Train, and Cascade Laboratories. Use Manufacturing West for uncollected fixed nodes and The Train for a repeatable Portal World loop. Facility resource nodes do not normally respawn unless the save enables Simple Loot Respawning; resource nodes inside Portal Worlds can return through the normal Portal World reset.

Steel Cable workflow

1. Count the cable required by the selected recipe or upgrade.
2. Check reachable Manufacturing West Mine Crates that have not been broken in the current save.
3. If repeatable cable is required, enter The Train after confirming its reset state and target Mine Crates specifically.
4. Break a crate, collect the guaranteed cable, and treat wood, cloth, discs, chain, rebar, hose, or a pickaxe as optional secondary results.
5. Leave once the cable quota is met or inventory weight threatens extraction.

The Blacksmith also trades one Steel Cable for one Military Electronics. Use that conversion only when the cable unlock is more valuable than preserving the Military Electronics for its own recipes.

Refined Carbon: choose salvage or exchange

Refined Carbon has three documented acquisition categories:

• break a Carbon Analysis Machine;
• salvage a Riot Shield or Lump of Coal;
• exchange Silver Scrap at the Quantum Exchanger near the Cellular Lab in Cascade Laboratories.

Do not describe all Order armor as a carbon source. The current Refined Carbon page specifically names the Riot Shield, while the Riot Shield page identifies Rooks and Shield Troopers as its enemy sources.

Refined Carbon decision

At the exchanger, drop Silver Scrap into the input chute and collect the Refined Carbon from the output. Confirm the machine display before depositing anything; the facility contains several exchangers with different input-output pairs.

Optic Lens: Blacksmith exchange

The current Optic Lens page lists two acquisition paths. The predictable path is the Blacksmith's exchange of one Reinforced Hose for one Optic Lens. The salvage path uses a Smashed GATE NVGs or Wessex Rifle.

Optic Lens workflow

1. Confirm that the Blacksmith is available in Manufacturing West.
2. Count the lenses required for the exact progression repair or craft.
3. Open the current Reinforced Hose recipe and gather only its listed inputs, or obtain a hose through Marion or a Plant Toolbox as the item page allows.
4. Trade one Reinforced Hose for one Optic Lens.
5. Repeat only until the lens quota is met; Reinforced Hoses have other uses.

The trade is an unlockable fixed exchange, not a random rotating stock row. Waiting for a vendor refresh will not solve a missing unlock. If the row is not visible, verify the relevant story conversation and progression state. Salvage is the fallback only when one of the two documented source items is expendable.

Canister: Fire Extinguisher salvage

The material is named Canister on the current item page. It is obtained by salvaging a Fire Extinguisher at a Repair and Salvage Station. An extinguisher is not a container with a chance to hold a Canister.

Fire Extinguishers have documented placed locations throughout Manufacturing West, Cascade Laboratories, The Train, and Fragments. The extinguisher page says the item has no current use while its salvage components do, so dismantling one is the intended conversion when a Canister is needed.

Canister workflow

1. Check storage for a Fire Extinguisher already brought to base.
2. If none is available, choose a documented sector or The Train location that is already on the current progression route.
3. Pick up the extinguisher and return it to a Repair and Salvage Station.
4. Salvage it and secure the resulting Canister before sorting side materials.
5. Use The Train after a Portal World reset when a repeatable placed source is needed; do not wait for fixed facility extinguishers to respawn in a default save.

Combined run rules

Combining routes is useful only when one trip naturally passes two verified sources. For example, The Train can provide both Mine Crates and placed Fire Extinguishers. It does not turn every train car or cargo container into a cable node, and it does not guarantee that a previously collected extinguisher has returned unless the world reset completed.

Use this preparation table before a combined trip:

Failure recovery

Renewal check before another run

Do not repeat a route until its source can actually exist again. For The Train, confirm that the Portal World reset completed and that no player occupied the world during the reset window. For Manufacturing West, Cascade Laboratories, and other facility sectors, assume a collected node or placed extinguisher remains gone unless the save explicitly enables Simple Loot Respawning. Trades and salvage conversions depend on obtaining another input item rather than on a timer. This check prevents an empty second trip from being misread as bad luck.

Record the source state beside the material quota: uncollected facility node, reset Portal World node, available exchange input, or owned salvage item. A route is ready to repeat only when one of those states is true.

Completion condition

The route is complete when the exact target quantity reaches storage, the input trade or salvage items are accounted for, and the player can identify which source is renewable in the current save. Do not turn one successful trip into a universal per-run yield. Mine Crates guarantee their cable, but route availability, Portal World reset state, already-collected placed items, and player inventory still determine the actual return.

For a cable-only repeatable route, continue with the Train World Steel Cable guide. For a wider exchange plan, use the trader locations guide.
