The Online Pass found within copies of Ubisoft’s grants access to the game’s online mode and use of an exclusive character. Eurogamer reports that upon activating the Uplay Passport code found within new copies of the game, access to the multiplayer modes is immediately granted.
Those who buy the game pre-owned version will, obviously, not be able to access the content without paying Ubisoft for a new Passport by purchasing it from Xbox Live or PSN.
Assassin’s Creed: Revelations is released in the UK today.
