Several of Arkham City's prisoners mention that Blackgate was rumored to have been converted into a shopping mall yet these rumors are never confirmed. The prisoners act as soldiers to Joker, Two-Face and Penguin, though some are without a faction and act as both a source of information and entertainment if the player chooses to listen to their conversations. On a related note, some of the prisoners that are seen working for the three villains secretly work for Riddler as Batman would often interrogate them in order to access the Riddler's Challenge Maps.
