A new trailer for Batman: Arkham Knight has been released by Rocksteady, and it features a couple of minutes of gameplay which takes place at the Ace Chemicals Plant. In this segment Batman is trying to rescue some employees of Ace, but has the small problem of an army standing between him and his goal. Gone are the thugs with pipes and machine guns, replaced with a private military firm that has helicopters and tanks.
This army is led by the mysterious Arkham Knight who has been active around the world apparently, leading this force though not letting any of his soldiers know his real identity. Scarecrow is mentioned quite often too with suggestions that he and the Arkham Knight are working together to bring down Batman and Gotham. The trailer also shows the Batmobile in action, showing how smooth it seems to be to transition between that and going around on foot. I’m quite liking the look of the vehicle combat personally.
