Ubisoft's Uplay Passport, a one-time-use code in new games that grants access to online features, will not be included in any future games and is being stripped from Assassin's Creed 4: Black Flag.

"The Uplay Passport program was initiated as a means of giving customers full access and support for online multiplayer and features, along with exclusive content, bonuses and rewards," Ubisoft writes. "However, games today are blurring the line between offline and online, between what is 'single player' and what is 'multiplayer.' Based on that and on the feedback we received from you, we recognized that Passport is no longer the best approach for ensuring that all our customers have the best possible experience with all facets of our games."

Uplay in Black Flag restricted single-player access to the game's fleet management system, Ubisoft confirmed. Ubisoft is eliminating the cost of the Uplay Passport in Black Flag - those without one can download a code for free via Xbox Live or PSN, and those who already bought one can contact regional Ubisoft support for more information.
