Now prepare to sit down, relax and watch a brutal vigilante dole out justice on various criminal faces as if morality were going out of style. It’s the latest Batman Arkham Knight trailer, as the caped crusader shifts away from the Ace Chemicals mission of last week and gets ready for an all new challenge. At Ace Chemicals again. Well ok then.
