CEO at the time, Steve Jobs, revealed the development of the game in his keynote speech on 9 September 2009. The game was released for the Nintendo DS and iOS. Both iPhone and DSi users are able to use their devices' camera function to display portrait photographs as wanted posters in-game. The iOS version was removed from the App Store sometime in 2013.
