Batman Arkham City's Robin DLC will be available to UK gamers through pre-orders at Game and Gamestation.
The extra content sees sidekick Robin playable in the Arkham City's Challenge Mode.
It also adds two maps: Black Mask Hideout and Freight Train Escape.
The Robin DLC pack was previously spotted as a US pre-order bonus. Across the pond it's only available through retailer Best Buy.
Batman: Arkham City will feature a wide array of bolt-on content - a total of six Batman pre-order skins are set to be divvied up between various retailers.
Even supermarket behemoth Tesco is involved. It has the UK pre-order exclusive for the four hour-long Joker's Carnival Challenge Map.
