I love Batman: Arkham City. Seriously. In my opinion it's one of the best games in the past 5 years. But there were so many characters in Rocksteady's game that it could feel like a few of them didn't get the screen time they deserve. Hopefully that'll change soon.
A list of PlayStation 3 trophies discovered by PS3 Trophies suggests that Robin will be getting some campaign action in upcoming DLC. These 10 achievements will be reportedly bundled as "Harley's Revenge" and include the Boy Wonder's name and weapons in the descriptions. The list includes:
Lost Properties: No crimefighter should be without this.
Breaking and Entering: Find a way into the secret base.
How's It Hanging?: Clean up the Dry Docks.
The Last Laugh?: The joke's on who?
Frequent Flyer: Zip Kick 3 different thugs.
Battering Ram: Shield Bash 5 different thugs.
Snap To It: Snap Flash an unarmed thug, an environmental object and a Titan.
Bomb Squad: Defuse all bombs in 3 minutes or less.
A Few New Tricks: Use 5 different Quickfire gadgets in one fight as Robin in Harley Quinn's Revenge.
Party's Over: Destroy all Harley Balloons.
The Rocksteady team hasn't exactly ruled out single-player DLC, and obviously like to support Challenge Mode with new maps and characters. This seems like a bit of both. We'll be sure to give you the official word when it lands... possibly at PAX East!
