I took out my first Predator. He kept healing himself, which was annoying but not incapable of defeating him. Found my friend who has a Xeno inside her but someone on the walkie talkie claims to being able to get it out of her.
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!
