re: a couple of people have said this but the actual M134 isnt that loud, its hard to recreate the actual sound in ofp but it isnt that loud, i cant describe the sound exactly but fromtv documentry's etc it sounds like a very quiet extremely fast whirring, if youve ever played DF:BHD the m134 on there shows that it should be 'around' this type of sound, theirs doesnt seem too accurate to me but its close enough, its definately not a scarily loud gun.
Ummm, the littlebirds guns are extreamly loud, the ones in DFBHD are not even close to the sound they make. Miniguns (M134s sound like a pager on vibraition mode going off on a wood table. But 100x louder.) I hope the BAS team will fix this in the future, but I know it will be hard to do.
BAS Keep up the good work
