The British Board of Film Classification has posted details about Batman: Arkham City's narrative on its official website, a week before the game is officially released.
The BBFC board never reveals Extended Classification Information when it decides on a film's - or in this case game's - rating, posting them online at a later date instead, NowGamer reports.
This information regarding the eagerly anticipated sequel to Batman: Arkham Asylum has now gone live, describing a plot point that has huge implications for one of the game's many villains.
Warner Bros. and Rocksteady have tried to keep as much of a lid as possible about details concerning the game, although rumours concerning the involvement of Robin and Nightwinf were leaked earlier than intended.
There has also been tight security regarding the posting of reviews, for which an embargo is in place until 3pm BST on October 14, although some have naturally come out, all praising the game as one of the greatest titles in video history.
Batman: Arkham City is released on XBox 360 and PS3 on October 21, coming to the PC in November.
