How to activate trigger when zombie horde killed after being spawned by module?
Pretty much the title, I am trying to have an ALiVE CAS module spawn from a trigger that should activate when the last zombie dies... I got everything set up except I don't know how to determine when the horde is destroyed. I figured since I'm using the ryans zombies and demons spawn module to do this I should ask here!

I'm using RyanZM_modulespawn ( I sync this to a zombie waypoint module to get the horde to move, right?) and then trying to have them advance on an airfield with a tower turret and some seriously unlucky dudes hoping for a helicopter. So far all I've got in the single trigger for the spot is :

["CAS",[[1902.023,3471.073,10.610],76.211,"B_CUPS_AH64D_USA","Phantom 1","",""]] Call ALiVE_fnc_combatSupportAdd;

in the "on activation" field.
