After Origins seemed to be treading water, Arkham Knight feels like a bold new step into the future. The exploration is more satisfying than in City, the story is gripping with that central ‘who is the Arkham Knight?’ plot, and the whole thing is properly knock-out gorgeous – Batman’s cape flaps and flutters in the breeze, battered by the rain, as the lights of Gotham city shimmer through the mist.
