Mixed Signals

Have you spotted any Surveyors; the big round ones? They seem to be transmitting data back into orbit, and I can't help but think it's tied to that signal we picked up. Will you break one open, so we can try to decipher the data?

Objectives

1.
Destroy an ARC Surveyor
2.
Obtain 1 Surveyor Vault

All objectives carry over between raids. You do not need to complete everything in a single run.

Walkthrough Tips

Combat objectives can be completed across multiple raids if needed. Progress persists between sessions, so retreat if overwhelmed rather than losing your gear.

This quest grants you specific items upon acceptance. These are typically required for one or more objectives, so don't discard them.

This quest is part of a chain. Completing the previous quest(s) in the series is required before this one becomes available from the trader.

Recommended Loadout

Ranged Weapon (Assault Rifle or SMG)

Combat objectives require reliable damage output at medium range. An assault rifle gives you versatility against both ground and aerial ARC units.

Grenades (Shrapnel or Snap Blast)

Grenades help clear clustered ARC groups quickly, reducing the time you spend exposed during combat phases.

Zipline

Ziplines speed up navigation between objectives spread across the map. Place them on high points to create shortcuts for return trips.

Step-by-Step Completion Guide

Follow these steps to complete all objectives for Mixed Signals. Each step includes contextual advice based on the objective type.

1

Destroy an ARC Surveyor

Engage the specified enemies using your weapons. Progress counts across multiple raids, so retreat if your health is low rather than risking a gear loss. ARC machines have weak points that deal bonus damage when hit.

2

Obtain 1 Surveyor Vault

Collect the specified items from the environment or from defeated enemies. These spawns may be randomized, so check multiple locations within the objective zone.

Map: Buried City

An urban ruin partially swallowed by shifting earth and time. Narrow streets, collapsed buildings, and underground passages create a maze-like combat environment. Visibility is limited and ambush opportunities are everywhere, both for Raiders and ARC forces.

Navigation is the biggest challenge here. Mark your entry points and keep track of elevation changes. Underground sections can loop back on themselves. ARC Rollers are common in the tighter corridors.
