Hi all. Sorry for the title, it may confuse you. I had no idea how to put it. But I've recently started playing the game, and I've just unlocked the ability to have kenways fleet. Anyway it gave a timer for how long it would take for missions to complete etc, but once all that mini tutorial was done it said play with friends to make misisons easier etc. This has confused me somewhat as the singleplayer isn't co op. So what exactly did that mean about having friends help out? I have absolutely no idea. Is it's xbox companion or through online multiplayer? Any help with this confusion would be great.
