Within the games lore,
The predators used a device of somekind that disabled the predator tech that the owlf had stored,
That would be a relatively easy gear item to implement,
It would be a area of effect item,
That would stop the fireteams various devices that track the predator,
And scan the area.
You could have it effect the items they’ve already layed down,
and the items they have in their inventory for a limited amount of time.
Make it a 4 or 5 on the gear stat,
That will give people a reason to use the few predators that have 15 gear attributes,
Which currently go unused,
