Well, started playing the main quest which I should be able to finish the game on the next go around. I had to take out a lot of guards, along with shadow(in) figures. Tough level..
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!
