Is there Batman: Arkham City DLC on the way? The image above was tweeted out by Rocksteady along with text reading:
So excited to see all the speculation around our tease today @arkhamcitynews.
As a man who loves to speculate, I'd like to point out that it's Harley Quinn with a freakin' sledgehammer. Also: A ton of PS3 trophies mentioning ol' Harley were posted on the internet back at the beginning of the month. We'll let you know more when we know more.
