The Batman Arkham Facebook page has teased an announcement on December 31st with the above image.
The update reads:
"Visit this page on December 31st for a special announcement…more details to come next week!"
It's unclear whether the announcement will be of a new game or of a DLC for Batman Arkham Origins. The image recalls BioShock 1 and 2's iconic art deco setting in the underwater city of Rapture and maybe we'll be getting a crossover of some kind. We can always dream, right?
Do you have any ideas about what Warner Bros. might be cooking?
