The real tragedy here was the fate of the Sonics . <| sep |> Great work you guys ! Here ' s what I ' m thinkingAfter the three successful scans , we need to find out what has changed or opened . It ' s pretty doubtful there ' s anything in that actual room due to the layout and height of the ceiling , etc . After the third remnant is killed , you have to activate the monitor again to start the countdown . My money is on there being an alternate path during that frantic run out of the tunnel , considering the mission ends once you exit and the door closes . If there is anything , it pretty much has to be during that run . Some options could be a new platform or cliff somewhere around that bridge between the two chambers . That always struck me as an odd design , such an open space that doesn ' t really serve a purpose why not just make the tunnel longer ? can you scan without killing the remnants ? If so , is it possible to backtrack after scanning , without initiating the countdown ? is it possible that this has something to do with the raid artifacts as opposed to the Iron Lord artifacts ? Maybe something more obvious happens if you scan with those equipped . Just some thoughts . I was big on the Wretched Eye , but that ended up all speculation . This actually seems like something .
