If you look closely, underneath the weapon it says "Future War Cult". This makes me wonder if certain weapons will only be available for use by different factions. Or maybe your weapon skin changes with your faction (assuming you have one), letting everyone use all of the weapons. Having some weapons be faction specific might make faction wars more interesting. This also brings up the question of what types of weapons that will be faction specific. I would assume that all the factions have their own type of all the weapon classes. Another thing could be that factions provide different skill tree options for weapons. This seems more far fetched to me, but it is a possibility. Thoughts?
