Batman Arkham Knight Trailer Reveals New Mechanic

Arkham Knight is the last installment in Rocksteady's Batman series. The new trailer features many characters from the batman universe like Robin, Nightwing, Catwoman, and Azrael. The first three incorporates a system called duel play. I'm not sure what this means, but it looks like a system reminiscent of GTA5's different playable characters. Azrael is a villian who made small appearances in Arkham City during a side quest. Arkham Knight comes out on June 23rd, but for now enjoy the trailer.
