Had some major difficulty in a few spots.. a rotating malfunctioning laser kept cutting me in half; along with multiple alien lifeforms. I had to double back and sell some stuff to get med packs. I finally got through it with enough careful planning.

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!
