I have failed multiple times doing this Solo without a fireteam. Today I found 2 guys (one new, prob hadn't done it) and one that may or may not have done it). We started the first quest and it worked flawlessly. Previously when I started the quest it would bug the quest title to Escalation Protocol and it wouldn't finish. It didn't do that today and I got the mark to complete the first (top quest). Will update you later as I complete it
