In the new (and M-Rated!) Batman: Arkham installment from Rocksteady, Batman seems to be facing his largest adversary yet: the army of Scarecrow. But, if you're kickass like Batman, then it doesn't matter whether you have an army to fight. What matters, is protecting the innocent of Gotham. All of which is on display in this new trailer for Batman: Arkham Knight, entitled "All Who Follow You" .
