Good lord in heaven, this game is difficult... The military parts that is. And I'm loving it, because this is how it should feel like to fight a trained military force.
The only thing I hate, is the fact that the moments with the epic music are often the hardest parts. So when the music starts I'm all "Aw yeah, lets kill some sons of bitche- oh wait, I'm dead."
Oh, and you can download the soundtrack
