We suppose we should assert that the video above contains minor spoilers for those that have not yet played or completed Batman: Arkham City (like our own resident jerk, Sean Aune). Although, the name of this DLC, "Harley Quinn's Revenge," is almost spoilerish in and of itself.

I will say this about the upcoming DLC… I absolutely love that its grounded in actual plot and story rather than nothing more than a pack of challenge maps and costumes. Not that I don't appreciate the extra areas for Bats to clear, but I'd much rather have story content available than just fighting content.

Hopefully it's as exceptionally written and handled as the original Arkham City dramatic.

The DLC will be available for the Xbox 360 and PlayStation 3 platforms on May 29th.
