I would love to know the answer to this. I'm not seeing mods for sale from Banshee like all the Google articles say. So what gives? Do I need to be a specific guardian rank or do some intro mission before I can purchase them? I'm a new player and find it strange the answer to these questions is nowhere to be seen. I'm not sure if you're having that same issue, but I can't even purchase them from the vendors that are supposed to sell them.
