New game comes with an online pass that is necessary to get access to the Catwoman part in the Arkham City. Those who don’t have the pass i.e they didn’t buy the new game will still be able to play the single player normally and complete the game but they won’t be able to play the 4 story-based missions associated with Catwoman as a playable character.
The pass code is also required to unlock Catwoman as a playable character in challenge mode. I don’t think you would like the game without the spice of the Catwoman. Would you?
Batman Arkham City will hit stores shelves on October 18.
