Earlier this month, a list of 10 new trophies appeared on the website ps3trophies.org that suggested Batman: Arkham City would be getting new downloadable content that would add to the story. The trophies seemed to suggest that the downloadable content would center around Batmans partner, Robin, and villain, Harley Quinn. This seems to have been backed up officially today, thanks to a new teaser being poster on the games official Twitter account.
Could this new downloadable content also give a bit more detail about the twist ending with Harley Quinn on Batman: Arkham City? Hopefully this tease is an indication that an announcement is coming soon!
