Why Players Search It

Players usually search the Sonic Resonator Upgrade after finding a structure that does not respond to normal interaction. That is a progression clue, not a reason to brute-force the area.

Check the tool or upgrade chain, then return when you can interact correctly.

Angel Comb Connection

Angel Comb-style routes reward preparation. If the center does not respond, look for linked targets, missing tool progress, or nearby route steps.

Trip Planning

Bring enough oxygen and inventory space to check nearby materials after the interaction. Do not leave a useful route without scanning plants or markers around it.

How To Use This Page

Use this page when progression feels blocked by depth, vehicle capability, a structure, or an upgrade chain. The goal is to identify the next safe unlock, not to rush the deepest route available.

Progression pages should be checked against current build behavior and official update notes.

Before You Act On This Guide

  • Identify the route or objective the upgrade unlocks.
  • Check every rare material in the upgrade chain.
  • Scout after installing an upgrade before farming.
  • Keep enough reserve material for the next module.

Pause if the upgrade requires rare materials but you cannot name the route it will unlock.
