Made it past the hideout, Styx's assassination attempt, the doomed souls, and now onto Conflagration 2/4. Still need to find some more knives, amber, and health.. Also, if you do not get the sneaking just right, you could find yourself in a no-win situation. Lot's of reloads unfortunately.
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!
