The new Batman: Arkham Knight trailer is a bit of a tease, really. On first viewing it seems to indicate co-operative play in the main campaign, letting friends take control of Nightwing, Robin and Catwoman in order to lend a hand, a frankly drool-inducing idea.

But nope, that’s not the case at all. Instead the new trailer shows off what Rocksteady have called Dual Play which will “allow players to seamlessly switch between The Dark Knight and his allies including Robin, Nightwing, and Catwoman in FreeFlow Combat. ”  Essentially it seems like you’ll get to play through some sections with AI partners and these moves provide a fun addition to the combat.

Meanwhile the trailer does game up a look at the returning Azrael who looks set to play a bit part in the game.

It is Batman. It is Rocksteady. I’m already sold.
