Phantom skins
I do not own phantom edition, but I have skins unlocked, happened with todays update: 1.0.1.0. I own the game on Steam
Ideas
I don't think a lot of people realize that if they have the EA subscription, they get the phantom pack with it.
That could be the case for some but in this case it's just appearing in mine and some peoples inventories without paying for anything except the base game. I have never had an EA subscription and i bought the base game on Steam. I have all the exclusive items in my inventory ingame
