New, free downloadable content will be coming to Batman: Arkham Asylum on September 17, according to the Playstation 3's in-game news ticker.
I don't have a copy of the game for the Xbox 360 or PC, so I haven't been able to see if the same news is popping up on those games. If you have either, feel free to check it out and let us know in comments.
Since it's the PS3 version, which already has a limited playable Joker in it, what sort of content do you think gamers may be getting next week?
My money is on new challenge rooms.
We've contacted Warner Bros. to see if they can enlighten us.
