The game is unplayable. In its current state there's no way to finish 100%. They released a patch which fixed nothing at all, and broke even more story missions and various quests. The patch was huge and all it did was literally change the version number. If you feel like losing your save games, and restarting after 80 or more hours be my guest. But I highly recommend not wasting your money on this title, nor any Ubisoft titles anymore. The company clearly does not care about their games. Nor do they support them. Don't believe me, check their forums. Over 10k bugs reported daily and no one responds or acknowledges them.
