It's just a sound....It's not just a sound it's THE sound!
I played the SP the other day and after killing the first enemy there was no sound...I sat in the corner crying for 20 mins and it was only when the doorbell rang that I had the strength to carry on.
I don't know if it was my computer or anything but when I watch 1 trailer with no music just the gameplay sound when I heard it it sounded almost exactly the same but I noticed it did sound a tad different c 4 yourself on PsGlitchers page on youtube he has 1 video where you can here the sound & to me it sounds a little different.
It kinda sounds different than uncharted 2's sound. Look on 1:23 & 1:44 of the video doesn't sound a little different? I mean it's pretty much the same. C 4 yourself.
