The part three trailer showing the "Ace Chemicals Infiltration" in Batman: Arkham Knight is now available, continuing this look at the continuation of the superhero series from Rocksteady Games. Here's word on how this three-part video series concludes: "In the final chapter, Batman pushes his combat skills and the Batmobile to the limit as he takes on a room full of armed mercenaries, then faces off against the Arkham Knight’s Automated Gunship. In addition, the new visual features a first look at the Sony PlayStation 4 exclusive Scarecrow Nightmare Mission Pack in which Gotham City falls victim to Scarecrow's fear toxin, transforming the famous city into a twisted nightmare."
