This latest Arkham Knight trailer “All Who Follow You” is all about Batman’s allies, and in this commentary writer and lifelong Bat-fan talks us through ex-Robins, a former Batgirl and the Azrael. We also get a brief look at the Dual Play mechanic which allows the player to switch between Batman and his allies during combat. Arkham Knight is out 23 June this year for PS4, XBox One and PC. There’s even a conspiracy theory about Johnny Charisma and Scarecrow’s original Jonathan Crane name — possibly with an illusion to the Jesus Christ messianic figure.
