Finally found a way around my previous hiccup. Now I think I am approaching the end. The enemy attacks are coming fast and frequent now. I dread what comes next. And oh, had to kill Stross who totally flipped out on us.
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!
