I love the feel of the game. I'm early on in the single player stages... I just finished rescuing the 2nd British guy. I'm playing on the second level right now... and it hasn't been all that difficult. So even if I finish this fairly soon.. I can move up to a harder level and try it again.

I think the sound effects and environment are awesome. There is a great deal of immersion effect in this game. I look forward to trying it out online sometime.
