It's been a while since we picked up Batman: Arkham City, however if a rogue tweet from the official Twitter account is anything to go by, we'll have a reason to pick it up again soon.
The tweet revealed the above screenshot, followed by an unattributed quote:
Don't worry. This is all part of my plan."
We're putting our money of Harley Quinn, given her propensity for large mallets of destruction. We'll keep you posted as we await official word from Warner Bros. Interactive Entertainment.
