Actually a step down from the original
While the game is just as enjoyable as the original in terms of gameplay, the sound is absolutely HORRIBLE! The gunfire is one of the most annoying sounds that I've heard in a long while, and that alone detracts a great deal from the quality of an otherwise awesome game. If you fixed that, than this would be an easy 9 or 10. As it is now though, I don't even want to play it anymore, the sound's so annoying.
