Did anyone here about the microtransactions and some content/chest being only obtainable if you have the companion app? There was an ign article on that somewhere, where a guy was having trouble opening chest. One needed the app, the other required an initiates account and the other required him to have a certain lockpick skill, he upgraded his lockpicking skill and still wasn't able to open it.
Not sure if I want to pick this up, Black Flag felt something of a chore to me, which is why I wasn't even Be to finish it yet.
