After releasing Part One and Part Two of "Batman: Arkham Knight's" Ace Chemicals Infiltration trailer, Rocksteady and Warner Bros. Interactive released the final piece of the trailer, which showcases the improved free-flow combat system of the upcoming game. It also presents a new look at the "Arkham Knight" version a fan-favorite villain from the very beginnings of the "Arkham" series: the Scarecrow. As Batman takes down individual enemies, the trailer culminates in the Dark Knight facing off against an attack helicopter with the aid of the Batmobile.

The trailer also has the first look at the PlayStation 4-exclusive Scarecrow Nightmare downloadable content, which seems to follow the traditional Scarecrow levels of both "Arkham Asylum" and "Arkham City."
