The latest trailer for the sure-fire smash-hit Batman: Arkham Knight offers glimpses at Robin, Nightwing and Azrael in a Gotham City besieged by conflict.

Check out the "All Who Follow You" trailer here.

Analysing footage from the trailer, there's a heavy emphasis on co-operative finishing moves between Robin, Catwoman, Nightwing and Batman, as they fight their way through vast armies of violent criminals and shady organisations. The footage has led many to speculate that Arkham Knight will feature co-op, but in a statement offered to Eurogamer, it seems that what we're seeing is a new "free-flow combat" mechanic, which allows the player to switch between Batman and his allies seamlessly and perform moves in tandem.

Both Red Hood and Harley Quinn are known to be the playable stars of their own DLCs, and the fiery anti-hero Azrael makes an appearance in the trailer. It remains to be seen whether these characters will be playable in the campaign, but one can always hope.

Arkham Knight takes place a year after the events of Arkham City. Batman is bereft of his arch-nemesis The Joker, and is adjusting to life without such chaos. The calm allows a super-villain contingent led by The Scarecrow to muster a new plan to finish Batman once and for all, supported by the mysterious Arkham Knight, who is best described as the anti-Batman, complete with a deep hatred of the Dark Knight, and an arsenal of lethal military hardware.

Arkham Knight closes the Arkham trilogy kick-started by Rocksteady Games and Warner Brothers back on the Xbox 360. The action-adventure game with Metroidvania elements has consistently enjoyed critical acclaim, and given the inclusion of an upgradable Batmobile, a play area 5 times larger than Arkham City and a whole host of new gadgets, gizmos, abilities and enemies, it seems likely that Rocksteady will end the trilogy with a loud, thunderous bang. Yeah, I'm hyped.

Batman: Arkham Knight launches June 23rd, 2015 on Xbox One, PS4 and PC.
