Sometimes the trophies or achiements can give away what's up coming for a game. And if ps3trophies.org
is to be believed, the new DLC will feature a story of Harley Quinn and perhaps Robin as a playable character.
Now Robin was only available as a challenge mode participant, but the new DLC could see him in action in the streets of Arkham City should this list of trophies be accurate.
I've really missed time wandering around in Batman: Arkham City
, so let's hope we hear news on this DLC soon. I'm itching to get back and if I can use Robin in the story mode, all the better.
