Rocksteady's Batman: Arkham City has an easter egg that even "The World's Greatest Detective" (AKA: Batman) might have struggled to find, players have discovered. A recent YouTube video from the channel "Batman Arkham Videos" (embedded above) has revealed a secret message in Arkham City that not only went undiscovered for three years, but required developer intervention to discover.
Turns out, if you set your Xbox 360, PS3 or PC's clock to December 13, 2004 - the day Sefton Hill and Jamie Walker founded Rocksteady - you'll trigger a unique monologue from Calendar Man. After talking about how he's been there "from the beginning," the date-obsessed villain warns that "the end of days is coming."
If you think this story sounds familiar, that's because it also took a nudge from Rocksteady to reveal an easter egg hidden in Batman: Arkham Asylum. In that case, the secret was a room stuffed full of references and teases to Arkham City. The uploader of this new video likewise theorizes that Calendar Man's cryptic message is a reference to the upcoming Batman: Arkham Knight.
You know, if a development team can slip these hidden bits of information past the Dark Knight and his followers so routinely, we have to wonder if Rocksteady might secretly be run by supervillains.
