"hooks" into the wider "Arkham-Verse", with a map hidden in a secret room.
Batman: Arkham Asylum has been championed as the great comic-to-videogame project ever, and Arkham City "sheds new light" on Asylum.
"While building Batman: Arkham Asylum, we placed a number of ‘hooks’ into the game that tie into the ‘Arkham-Verse’,” said narrative designer Paul Crocker.
"From the beginning we knew that Quincy was a bad guy, and planned what his next move would be. The room obviously ties into Arkham City, but to be fair, we hid it pretty well. We did assume that it would be found eventually and after following forum posts for 6 months or so, decided to announce it in the ‘Game of the Year’ podcast."
"The fans of the game have been amazing and again, reading the forums, we can see how much they value the efforts we have put into creating the background stories for the various characters and it was great to see all the posts and theories about the secret room once it was discovered."
"What I think people are really going to enjoy is not just how Arkham Asylum led to Arkham City, but also how the story in Arkham City sheds new light on the events you saw in Arkham Asylum," he continued.
Batman: Arkham City releases on Xbox 360, PS3 and PC in Fall 2011. Check the clip below to see what the hidden Warden's room looks like for yourself.
