Fireteam split to chase predator:
They need to be punished harshly in some way for splitting up and chasing a pred, maybe add a “fear” mechanic that if they are seperated from the squad the breating becomes heavy, heartbeat loud and destracting and the aim becomes wobbly untill they regroup with their team again to relative safety of others…
Audio decoys should play the stompy predator feet sounds as well as the normal pred sounds. they shouldnt play any fireteam voice lines as that gives away that its a decoy too easily.
