Just an interview with sound crew at DICE Gaming Studio that makes Battlefield: Bad Company 2 Vietnam game a journey back in time and place, to the 60's and the jungles of Vietnam. Nice article if you're intersted in sound design or overall audio aspects in computer games. I'm sure they had tons of fun recording the sounds. For example on one of the maps, you can hear the Vietnamese pig "Horace" oink from time to time ;)
That was a really old and really angry pig that I also met on my vacation. Every time you got close, he got a bit annoyed and squealed angrily, which I thought was pretty funny (he was on the other side of a fence). Well, you can't see him, only hear him. I made sure to mix the in-game sound to seem distant and unspecific, so the players don't assume that they will actually see the pig right in front of them.
