Batman: Arkham Knight" pre-order. The DLC actually seems interesting enough: you play as Harley Quinn in a prequel to the main Arkham Knight storyline featuring her attack on Nightwing's city to rescue Poison Ivy. That sounds fine. Harley is a great character even if her voice is mangled by an incompetent Tara Strong performance. Her relationship with Poison Ivy is one of the most interesting and complicated ones in all of Gotham. Plus Harley Quinn was apparently pregnant in "Arkham City" opening the door to all kinds of twists and emotional turns as she tries to get over the Joker. Harley plays very differently from Batman: she has no silent take-downs, but is more aggressive, faster, and can go berserker for one hit kills. This should be great.
Instead this DLC is crap. Allow me to give a summary of the entire thing: Harley beats up some cops, then goes into a room to beat up more cops with guns, then goes into another room to beat up cops without guns, then goes into another room to beat up cops with guns, then goes go an elevator shaft, and finally beats up a few cops backed up by Nightwing, and rescues Ivy. That's five fights total. How long does that take? Fifteen minutes. Now I paid nothing for this DLC because it was a pre-order bonus, but somehow even after an investment of nothing, I still feel ripped-off. This makes the worthless blue balls of "Metal Gear Solid: Ground Zeroes" seem like a sixty hour JRPG like "Persona 3". Just as soon you feel like you understand the difference between Harley Quinn and Batman's playstyles, the DLC is over. This story mode is over so fast that I only ever got a chance to use one of Harley's gadgets, I do not even know what the other two do.
Okay, the game is lengthy in terms of Atari 2600 standards, but maybe the story makes it worth it? Nope. Harley Quinn's pregnancy storyline ends with no conclusion as Rocksteady decided to chicken out and retcon the pregnancy test you found in "Arkham City" as a false positive. Harley as a character gets to do nothing but make some quips here and there, argue with the Penguin over her intercom, and talks with Poison Ivy for ten seconds before the DLC just ends abruptly. Does any of this matter for the main story though? Not even in the slightest! Harley Quinn has barely anything to do in the main game. Even after she beat Nightwing in a fair fight (which is pretty badass) Batman takes her her with a single punch, no boss fight. I do not even think that the team behind this DLC even were in communication with the main Rocksteady team. We're told Harley is trying to save Poison Ivy for the Scarecrow's plan. Then in the main game, Poison Ivy wants nothing to do with Scarecrow's plan and does all she can to foil it!
So if this is the standard that Rocksteady is planning for the other DLC storylines to come, I'd say just save your money. Sure Batgirl looks sexy in her upcoming story, but seriously think twice. This is unacceptable for any price.
