Completed conflagration 3/4, now onto the 4th level. I was also persistent enough to complete the secondary objectives, though it was tough. A portion of the level required no dead bodies found or visual sight with the guards.
Alright! It was tough as I had a hunter alien on my heels the whole time, but I was able to reach Nicole, who was attached to the Marker. I defeated her (eventually) and made my escape with Ellie. What a cool game. Final boss and game ending! Great stream!
