Doing the daily and just got to the chamber outside where you fight the SABER shank. Running around scanning things when I realised there was a scan noise coming from somewhere near the huge glass window looking into the boss room. I searched everywhere but couldn't find anything to scan. I jumped up and the sound got quieter so I can only conclude that the scan is below, in the boss room. There must be some way to open the doors and enter that room and the daily heroic may be the key to solving it. Anyone have any theories/data on this? Notes: It's not the ghost or the terminal at the back of the room, I have done both and the noise is still happening. By following the noise I've traced it to the middle of the clearing in front of the big window at the bottom of the stairs. Hold out your ghost to hear the noise.
