Tesco reveals Arkham City freebie

The UK’s leading supermarket Tesco has landed the rights to a tasty freebie for Warner Interactive’s Batman: Arkham City.

Those who pre-order with the chain will be rewarded with the Joker’s Carnival Challenge Map DLC. The stand-alone mission set is said to add around four hours of additional gameplay to the title.

A code to download the content will be emailed out to customers around two days after the game ships. Those who pick up the game from in-store will find the code inside the box.

"Are you brave enough to step into the Joker’s house of fun?” the press release reads. Can you defeat armies of deranged killers in a fight to the finish, hosted by the clown prince of crime in a twisted game show where the only prize is survival?"
