A portion of a Game Informer interview with designer Chris Tremmel...

GI: How many farts will be recorded for this game? Do you guys have the grossest foley artist in the business? Do you throw away the microphones when you're done?

CT: We are looking into a system that takes a library of roughly 10-15 different samples and procedurally combines them to create an infinite amount of variety. You might be surprised at how many quality takes you can get in a single day. It’s far lower than I thought, simply due to the working conditions it creates. As for the microphones, no we don’t throw them away, they are rentals.
