The reason I reload so often when caught is that I am carrying a dagger that cannot parry blows. Also, most of the enemies have too much armor to penetrate. This is a very challenging stealth game..
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!
