Mr. Freeze returns, Ra's al Ghul and the League of Shadows has risen from the Lazarus Pit, Killer Croc is prowling a downed aircraft, and Mad Hatter is talking crazy at the GCPD building. New areas to explore and tasks to complete alongside capturing the villains.
In addition to the story DLC, also available will be the Arkham Asylum Batmobile skin and the Christian Bale costume he wore in Batman Begins.
The end of the video gives us a nice teaser for the future, when Dax Ginn asks Sefton Hill, "So Sefton, are you saying, categorically, that this is the end of the road for Rocksteady and Batman?"
And Hill's response is, "Well..."
The end of the game leaves the potential for more to come, probably with a wider DC Comics universe base- Arkham Knight had references to Lex Luthor and a really blatant homage ending reminiscent of the Frank Miller classic comic series The Dark Knight Returns- leading me to believe Bruce Wayne faked his death to go Batman full-time, and then they'll bring in at least Superman, if not all of the JLA, into the video game series.
