I hit my 1 hour mark. Will finish it later. Escorting Mia, my synthetic cyborg lady through the ship. She is susceptible to friendly fire (dang it).
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!
