This plug in will make the sonic trip alarms in The Hidden:source only make a sound if the hidden sets it off. Due to the fact that there was no hook for the trip alarms the alarms are set off when the hidden is in close proximity to the beam of the sonic alarm when it is set off.
Known Issues:
-If IRIS runs through the alarm and the hidden runs through immediately after the alarm will not be set off
-Occasionally the hidden can pounce through the alarm and the alarm wont be set off.
-I'd imagine a high pinging hidden would also occasionally not set it off
Overall it works pretty good though
