Hidden behind an unmarked, destructible wall in Warden Sharp's office is a secret room containing blueprints for Arkham City, Rocksteady teasing their sequel before it was even announced. No player found it. In August 2010, about a year after the game came out, Rocksteady's Paul Crocker gave up waiting and revealed it himself.

How to find it

In the Warden's office, spray explosive gel on the unmarked wall section to the right of the warden's portrait (no detective-vision crack shows) and detonate.
