In Kobayashi Maru 1.0, I have been able to customize my borg sounds in the C:\Program Files\Activision\Bridge Commander\sfx\Custom\AssimilationBeam folder. 
However, I have been unable to locate what activates these sounds when the Borg Cube/Sphere or Diamond enter the system. 
I want to add this feature to other Borg Vessels ie: Borg Tactical Cube, Tetra, etc.
I checked the following folders to no avail:
Scripts\Custom\Autoload (borg..BPSounds) 
Scripts\Custom\Ships 
Scripts\Ships
Scripts\AI\Compound\BorgAttack
Normally I can locate the correct files and edit with no problem but I'm stumped on this one  :?  Any help would be appreciated :violin
