The Sound Design of Batman: Arkham City

Arkham City was so successful as it compiled some of the best people of their trade to work together. Paul Dini worked the script, Mark Hamill and Kevin Conroy took their place as the Joker and Batman.
Of course, sound was no exception.

In this article on Destructoid, some of the best sound designers explain the various processes they used. John Roesch was the Foley artist in Arkham City. He was also the artist in the Dark Knight, Matrix and Inception. It was interesting see him work, he uses anything to create the right sound. For example, to create the sound of bones breaking, he would break a leek in half. I didn't think it would work, but it does. This creative approach to sound design made some of the best sounds in the game.
