By next month, the two most iconic big-screen Batmobiles will have made it into Batman: Arkham Knight via DLC.

The 1989 Batmobile Pack, featuring the vehicle from Tim Burton's original film, is out now.

Next month will see the release of the Tumbler Batmobile Pack, which includes the street tank from Christopher Nolan's Dark Knight trilogy and two tracks inspired by the films.

September is also the target for six new AR challenges, and a story pack entitled GCPD Lockdown, in which players take on the role of Nightwing to prevent a breakout attempt by the Penguin.

WB has still not given a date for the promised PC performance patch.

All DLC packs are separate purchases except for players who purchased the Arkham Knight season pass.
