Wow thanks for the great feedback. I'm glad we inspired you to read up on the history behind the game. I hope you find it interesting.
Haha yes I hope you can make it to the end of the game. Don't forget in that room with the med pack, on chapter 2, you can break down the wall (t's in the description on the main game page) and use that to shoot through, it can be tricky to do but you can time it just right to shoot them as they come running past.
Have fun!
