Hopefully, someone will prove me wrong. But I don't find any value in crossbows. There is only 3 ammo, it doesn't hit hard. Why would I use it rather than a Deimos when I can have double damage ?
I guess that originally the crossbows were meant to be "silent". That would add a lot of value and make them relevant. The capacity of shooting stuff without getting "located" would go well with the "infiltration" logic.
Please make the crossbows "silent", even if it means lowering the damage.
