Players of the Payday series are called "Heisters".
"Scuzz Missile" by Tom Salta, which was featured in Need For Speed: Underground 2 intro was cut from the game due to licensing problems.
"Stone Cold" was the working title initially given to the game, but was scrapped when the developers feared trademark issues with the pro wrestler "Stone Cold" Steve Austin. The developers later considered "PAYDAY: Crime Wave" as the actual title, and finally settled on "PAYDAY: The Heist". Both "Stone Cold" and "Crime Wave" were recycled as the names of songs in the soundtrack; specifically, the themes for Green Bridge and Slaughterhouse respectively.
