I truly enjoyed playing this mod. It was very well done, though I am left wanting more. The story moved very fast in the background. It was a slightly nerve racking game, as it was much darker than the original, more true to life in that sense. I loved the way the monsters attacked and how guns were much more accurate. I would love to see more in this series. And it's free, so try it out. What do you have to lose? Only complaint is the formatting of the screen is messy, but once you find the proper resolution, everything is in the right place.
