"Last week, we speculated that Batman: Arkham City's Catwoman content would be bundled with new copies of the game, but that players buying the game used will need to purchase the character separately. Warner Bros. has now confirmed that to be the case.
As reported by Eurogamer, the Catwoman content will cost 800 Microsoft Points on Xbox 360, which is equivalent to $9.99 on PlayStation 3.
"Playing as Catwoman is not required to complete the game," Warner Bros. told Eurogamer.
Before confirmation came from Warner Bros., the online pass was revealed by leaked gameplay footage of the game's title screen, which reads, "Catwoman is a unique character with her own story, moves, and weapons. Unlock Catwoman by redeeming the [code] included in the game case or by visiting Xbox Live Marketplace."
The code will unlock four story scenes that feature Catwoman as a playable character, as well as unlocking her for use in the Riddler's Revenge challenge mode. Players will still encounter Catwoman if they play through the single-player campaign without redeeming the code, but the playthrough won't include missions that involve controlling her.
Batman: Arkham City hits stores on October 18th."
