Crossfire sounds, and effects

Hi, the other day I was checking out crossfire's files, to see what they got, cause sometimes they have some files and stuff that are going to be applied to the next patch, so I was checking it out.

SUDDENLY I SEEN SOMETHING CRAZY!! lol jk. But I listened to some of the sound effects and stuff like that give the area a certain feel... and I was like ... thats odd, I have never heard ANY of these in game, and I would love to.

They are located at
C:\Program Files\Z8Games\CrossFire\rez\Snd2\EnvSounds

I thought the lab ones are sick, but I tested it out while in game and I heard absolutely nothing . Does anyone hear these, or have z8 even put them in yet? And if not can you, cause that would be awesome ^^

Putting these in will make a minor difference, but I guarantee everyone would love to hear them, it would bring a nice effect to the game, instead of hearing nothing 24/7 except bullets and your own foot steps lol.
