Joker's Funland

"Welcome, inmates. You are now taking your first, tentative steps towards a better world. A world of fun, mischief and best of all, a world where the only person you need to answer to is yours truly."

- The Joker

Joker's Funland was the base of operations of The Joker and Harley Quinn in Batman: Arkham City. It was formerly the Sionis Industries Steel Mill before being taken over by The Clown Prince of Crime's gang and redecorated into a deadly amusement park. It was inhabited completely by Joker's clown henchmen and was the largest section of Arkham City controlled by any supervillain with the exception of Rā's al Ghūl's underground base in Wonder City.

Joker's Fun House was The Joker's headquarters within his large fortress where he mainly remained in obscurity while dying of a serious illness and planned his takeover of both Arkham City and Gotham City. The entrance to the Fun House used to be the Manager's Office within the Steel Mill, and was where Harley Quinn and The Joker stayed as she tended to his sickly condition.

Near the end of the game, Batman confronted The Joker (actually Clayface in disguise) in his Fun House and battled him along with his numerous gang members including Mr. Hammer and a Titan henchman. It was mostly destroyed by bombardment from TYGER helicopters after Professor Strange activated Protocol 10.

 * An altered version of Joker's Funland was featured as a DLC Challenge Map for those who preordered Arkham City under the name The Joker's Carnival. It was an arena fenced in and surrounded by bumper cars, flashing lights and various amusement park rides with carnival music playing in the background. In it, the player must fight an onslaught of The Joker's clown thugs as well as other inmates and gang members while The Joker spectates from the sidelines.
 * Joker's Fun House also appeared in the Challenge Maps under the name Funhouse Brawl.
