User blog comment:The.Outsider/AC3's multiplayer content to continue long after launch.../@comment-4043223-20120904160328/@comment-5266147-20120904171046

i understand what you mean that its not technicaly dlc as its more likely to be downloaded automaticaly as an update or summat, but i still do not really like the focus on MP content over SP, i have never been a fan of the MP element in the past games, but maybe the mew MP in ac3 will change my opinion of that.

about the xbox, it probably runs most of the game from disc and only stores a small amount on the hdd but the dlc will all need to fit on to the drive, best bet would be to remove anything you dont use regularly and/or upgrade to a larger hdd.
