Don't know if anyone else has noticed, but I was on patrol in the dreadnaught, at the founts, and noticed something weird. Instead of dropping down to the area where the 3 wardens are, I stayed up top and followed the path around to the opposite side. There's two rooms with 5 columns of crypts on the wall. In each column, all of the doors are lit up, except for one that blinks.
I don't know. Could be apart of a mission I haven't gotten to yet or what not, but just wondered if anyone else noticed this.
Also, at the end of the second room there's a door that I haven't seen open. Again could be nothing, but I'm hoping it's something.
Edit. As I went back to the founts I noticed the first room you come to has the same type of crypts blinking on the wall as well. So who knows lol.
Have you tried deploying your ghost when near the door? I know that some of those tombs that are on the ground (as if they've fallen) can be opened. Your ghost lights the doors & designates as "destructible." Melee or simply shoot them and you can walk right in. No one has seemed to post anything about these since I mentioned them weeks ago.
