I really enjoyed this game. It might have been hard (especially at the end), but I really enjoyed it. There is only two things I find wrong with this game. 1: You know the prototype armor you find near the end of the game? and you know how it has that special ability for running really fast? well, you should probably change the activation keys, for many a time, I found myself running headlong into a zombie, or falling into a pool of acid, when I was just trying to shift a little further on a platform, and instead, end up charging headlong off of it. Also, the game was a little short; I beat it in a day. Finnaly, I think you should be able to go back to the video at the beggining, and the video at the end, where sergei turns into the bug thing. Finnaly, I have one more requist: MEDALS!
