what mp3?? the one with dive dive shouting??
It's on the vp, extract it and save it as mp3 file... you might wanna add some more secs to the mp3 so it doesn't get that anoying, a guy screaming dive dive every 3 secs will get anyone very nervous.
I also remember some wav files that were like aditional releases, there's one where the same actor screams evade evade get out of there, but I guess they changed that one with the we have now on that mission.
