Upgrade station

Modification Station Guide

This page exists because "Modification Station" is a station search, not just a material search. Players need to know what route family it belongs to and which upgrades it gates before they chase every nearby resource.

Quick answer: Modification Station is the mid-game upgrade-station search tied to Tadpole modules, equipment upgrades, Celestine, Bioscanner planning, and Alien Ruins routes. Treat unlock and recipe details as in-game checks until station text is verified.

Step 1

Stabilize Alien Ruins access

The useful route context starts after Tadpole and Alien Ruins travel are no longer emergency trips.

Celestine is already mapped as a lower-depth route lead near the Alien Ruins side of the map.

Step 3

Use it as a planning station

Tie upgrades back to Tadpole modules, Bioscanner route, depth, and equipment needs.

Step 4

Do not copy upgrade tables

Publish station rows only after current-build text confirms unlock, cost, and effect.

Map and route leads

Use these markers as route-planning help, not as fixed spawn or recipe tables.

Questions people ask

What is the Modification Station for?

It is the mid-game upgrade station family tied to equipment, Tadpole modules, Bioscanner planning, and deeper route preparation.

Where should I look before chasing it?

Use Alien Ruins, Celestine, Tadpole depth, and module-route context before treating it as a simple base-object recipe.

Can we publish all upgrade costs now?

Not responsibly. Upgrade rows need current-build station text and patch version before becoming fixed table data.
