What this solves
Use this when the next route is not blocked by courage, but by air. The page connects tank recipes, Portable Oxygen Generator planning and the resources that usually stop oxygen progress.
Quick route
- Check which air tank or oxygen item is actually unlocked before farming.
- Use Silver for the first reliable oxygen step, then protect Lithium for portable backup.
- Delay Troilite and Atacamite spending until late oxygen and depth needs are clear.
- Open focused resource maps only for the material that blocks the current craft.
Before you go
- Know the recipe you are solving before entering a cave or trench.
- Keep one return landmark visible when testing a longer oxygen route.
- Do not spend late minerals on comfort crafts until the story or vehicle gate is clear.
Prerequisites
- Scanner path started
- Early Silver route understood
- Current air tank recipe checked
Field Notes
Step-by-step Walkthrough
Each step keeps exact coordinates conservative. Use the linked map filters for route planning and trust reviewed marker labels when you need precision.
Start oxygen planning from the blocked recipe, not from a general resource sweep. Step 1RecipeGuide noteStart from the blocked oxygen recipe
Choose the exact oxygen craft before farming materials.
Standard Air Tank, High Capacity Air Tank and later oxygen items pull from different material pressure points, so start with the recipe screen.
The fastest oxygen route starts with a boring question: what craft is blocking you right now? If the blocker is an early tank, Silver and starter resources matter most. If the blocker is portable backup or a late tank, Lithium, Atacamite or Troilite may matter more than another shallow sweep.
Checking the recipe first keeps the route small. You can open the exact resource page, check used-in links, then return to the map only for the material that matters.
Map hint
Use `/map?type=resource&q=Silver&mode=focused` for the first oxygen material wall.
Do this
- Blocked recipe identified
- Required resources listed
- One map filter selected
Watch for
- Farming every oxygen material at once
- Spending Silver before checking tank and wiring needs
Next: Open the Silver guide if the first tank or wiring path is still blocked.
Bank Lithium before spending it so oxygen backup and depth routes do not compete blindly. Step 2RecipeGuide noteTreat Portable Oxygen Generator as backup planning
Use Lithium and Titanium for route safety rather than random comfort.
Portable Oxygen Generator planning belongs after the basic oxygen loop works and the route needs a backup margin.
Portable Oxygen Generator is useful because it changes how much mistake margin a route has. It does not replace learning the exit path. Treat it as backup for caves, trenches and longer search areas after the early tank route is under control.
Lithium is the resource to protect here. If you find it while another route is active, bank it and check whether oxygen backup or depth progress needs it first.
Map hint
Open focused Lithium results only when the oxygen backup recipe is active.
Do this
- Lithium reserved
- Titanium route stable
- Return route still planned
Watch for
- Using portable backup as an excuse to ignore exits
Next: Use the Lithium resource page if portable backup is the next craft.
Late oxygen materials should be reserved until the route gate is clear. Step 3RecipePending reviewSave late oxygen materials until the route demands them
Avoid spending Troilite or Atacamite before late oxygen and story gates are understood.
Ultra High Capacity Air Tank and late oxygen comfort can compete with vehicle, power and ruin chains.
Late oxygen crafts can pull from the same material pool as vehicle depth, power and ruin progress. If Troilite or Atacamite appears in the chain, treat the choice as a route decision rather than a simple upgrade button.
When in doubt, read the Troilite warning first, then decide whether oxygen capacity, vehicle depth or the current story route gets the material.
Map hint
Use focused Troilite or Atacamite maps only after choosing the late craft.
Do this
- Late craft compared
- Troilite reserve checked
- Story route not blocked by the same material
Watch for
- Spending Troilite because the craft button is available
Next: Open the Troilite warning before using late material on oxygen comfort.
