Ubisoft is dropping its Uplay Passport online pass program for all future games. And it will effectively remove it from the just-released Assassin's Creed IV by providing the passes for free to all ACIV gamers, whether they get the game new or used.
The online pass program had required users of ACIV to input a code printed on a flyer packaged with each copy of the game. The code activated a variety of online features for the game's multiplayer and singleplayer modes. Some of those features made the game easier.
