Quick answer

  • Use the Modification Station blueprint layer on the map first; the current marker export includes 3 Modification Station scan markers.
  • After unlocking it, the current local recipe data builds the Modification Station with the Builder Tool using 2 Titanium, 2 Celestine, and 2 Copper.
  • Build it when a depth, tool, or Tadpole upgrade is your next blocker, then verify marker reachability and live recipe costs in your current build.

Modification Station blueprint map

Current Modification Station blueprint markers are scouting points, not a tested safest route. Pick a marker you can reach and return from, then verify the route in your save.

Open map

The Modification Station is the base module that turns mid-game materials into real progression. If you already have the Habitat Builder and are starting to collect Celestine, Enameled Glass, Conduit Crystal, Atacamite, or Troilite, plan this station before spending those materials on side crafts.

Start with a scan marker

The current map export includes 3 Modification Station blueprint markers. Use the map layer as a scouting tool:

  1. Open the Modification Station blueprint filter on the map.
  2. Choose the marker with the clearest return path from a landmark you already know.
  3. Bring a Scanner, enough oxygen margin, and the tools you normally use for deeper wreck or ruins checks.
  4. Scan until the blueprint unlocks.
  5. Leave and build the station before turning the trip into a long resource run.

If a marker drops into a route you cannot safely exit, do not force it. Come back after improving oxygen, vehicle depth, or route knowledge.

Build the station at your base

Once the blueprint is unlocked, the current local recipe data lists the Modification Station as a Builder Tool craft:

MaterialLocal costPractical note
Titanium2Keep some spare for room and base support pieces.
Celestine2Do not spend all early Celestine if Tadpole Depth Module Mk. 1 is also your goal.
Copper2Bring extra if you still need wiring or electronics for nearby crafts.

Place it in a powered base with enough room to open the upgrade menu without blocking storage or vehicle access. A small working base is enough; the station matters more than decorative expansion at this stage.

Choose the upgrade that solves the blocker

The current local blueprint export lists these Modification Station crafts:

UpgradeCurrent local costUse it when…
Tadpole Depth Module Mk. 13 Celestine, 2 Enameled Glass, 1 System ChipDeeper travel is blocking safer resource or blueprint trips.
Tadpole Depth Module Mk. 22 Dedicated Core, 2 Troilite, 2 Mangalloy IngotYou are past the first depth upgrade and need the next vehicle depth step.
Bioscanner1 Scanner, 2 Enameled Glass, 3 Conduit CrystalScanning progress or alien-tech checks are blocking you.
Feedback Resonator1 Sonic Resonator, 2 Enameled Glass, 2 Conduit Crystal, 2 StrontiumHardened material interactions are the blocker.
Echo Location3 Quartz, 1 Mild Acid, 1 AtacamiteYou need the upgraded location tool path before spending Atacamite elsewhere.
Engine Efficiency1 Titanium Ingot, 2 Glass, 1 System ChipVehicle efficiency is more important than depth or scanning right now.
Cavitation Muffler3 Titanium, 2 StrontiumTravel noise and creature pressure are the problem.
Strike Armor2 Enameled Glass, 2 StrontiumVehicle damage pressure is stopping repeated trips.
Photovoltaic Charger1 Copper Ingot, 1 Strong Acid, 1 TroilitePower management is blocking longer vehicle use.

Do not craft from the top of the list automatically. If depth is stopping you, save for Tadpole Depth Module Mk. 1 first. If scanning progress is stopping you, compare Bioscanner against your Conduit Crystal supply. If a route is dangerous because of creature pressure, the defensive or noise-control upgrades may matter more.

Quick checklist

  1. Open the Modification Station blueprint map layer.
  2. Pick one reachable scan marker, not the deepest-looking one.
  3. Bring a Scanner and leave enough oxygen to return.
  4. Scan until the Modification Station blueprint unlocks.
  5. Gather 2 Titanium, 2 Celestine, and 2 Copper.
  6. Build the Modification Station with the Builder Tool in a powered base.
  7. Check your real blocker: depth, scanning, hardened materials, vehicle safety, or power.
  8. Craft only the upgrade that solves that blocker.

Sources and current limits

Map, recipe, and upgrade guidance comes from the current item, blueprint, and marker data available to this site. Before relying on it as a final route, recheck scan count, marker reachability, depth, hazards, and recipe costs in your current build.
