Once upon a time I could get headshot after headshot with my pistol. I seem to become rusty. BTW, those enemies that turn invisible are a real pain in the butt and this game can be unforgiving.
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!
