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 headquarters of any supervillain contained within Arkham City with the exception of Ra's al Ghul's underground base in Wonder City. The two key areas within it were The Joker's Carnival, a combat arena where Joker could spectate his henchmen and other inmates engaging in brawls to the death for entertainment (available as DLC by preordering the game so that the player could play on it as a Challenge Map), and Joker's Fun House, the villain's hideout where he remained in obscurity for the majority of the time he was dealing with the illness that was killing him and planned his takeover of both Arkham City and Gotham City.
