Went through a couple of levels and met up with Cpt. Dylan. We defeated Doctor Proton and are getting ready to ride the antigravity lift..

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!
