History of Signal Seeker

Overview

Signal Seeker is a legacy Episode: Echoes Encore triumph. Solve the maze puzzle associated with the Destabilizing Rounds Refit catalyst chest for Choir of One. It also unlocks Vex Countermand collectibles.

How to complete

In the original setup, complete NES007 or join someone who has done so. Activate the optional portals near Encore's opening traversal: take the narrow left opening in the purple area and shoot each cube marked by a small cube beneath it, repeating for the outer portal cubes.

Before the final boss, access the Degaussed Exomind room's conflux and enter its portal. In the hub, take the left portal to the maze. Move its Vex modules between the available pedestals to open paths through the red barriers, reaching and activating all four switches. Finish the puzzle and claim its chest. This is separate from the opening cube puzzle for Nexus Access.
