Over three years have passed, and Batman: Arkham City remains one of most memorable if not THE BEST Batman game ever created. Developer Rocksteady Studios broke new ground with their 2011 sequel to Batman: Arkham Asylum, and allowed players to truly immerse themselves in Batman's world as he explored and interacted with a cornered off portion of Gotham City that became the new correctional facility for the criminally insane, which was headed and overseen by the manipulative Doctor Hugo Strange.
Now, it seems that more surprises still come from this critically acclaimed title, as a fan has discovered a BRAND NEW EASTER EGG that is associated with the date and holiday obsessed villain known as Julian Day, aka the "Calendar Man". Players could visit his cell during the midst of playing Arkham City, and if timed with a corresponding holiday in the calendar, he would tell one of his "grim stories" to The Dark Knight associated with the date itself.
Behold, via the official Batman Arkham Facebook page Calendar Man's new "Secret Message", and learn how the people who found it discover that it ties to, strangely enough, Rocksteady itself!
Batman: Arkham City is currently available for the PS3, Xbox 360, Wii U, PC, and Mac OSX!
