Outside of challenge maps, the only single player DLC for last year’s Batman: Arkham City was the day one Catwoman content. A new set of PS3 trophies however, hint at a new singe player DLC pack entitled “Harley’s Revenge”. It also suggests that Robin would be playable in this story extension, after making a brief campaign cameo and then being delegated to a challenge map only character. While the listings did come from a PS3 trophy listing, it is reasonable to assume that this content would be made available for both the Xbox 360 and PC platforms as well.

The breakdown of the trophy list is as follows:

• Lost Property (Bronze) – No crimefighter should be without this
• Breaking and Entering (Bronze) – Find a way into the secret base
• How’s It Hanging? (Silver) – Clean up the Dry Docks
• The Last Laugh (Silver) – The joke’s on who?
• Frequent Flyer (Bronze) – Zip Kick 3 different thugs
• Battering Ram (Bronze) – Shield Bash 5 different thugs
• Snap To It (Bronze) – Snap Flash an unarmed thug, an armed thug, an environmental object and a Titan
• Bomb Squad (Bronze) – Defuse all bombs in 3 minutes or less
• A Few New Tricks (Bronze) – Use 5 different Quickfire gadgets in one fight as Robin in Harley Quinn’s Revenge
• Party’s Over (Silver) – Destroy all Harley Balloons
