There are 8 key rings to be collected when playing as Mitch, 12 when playing as Eddie and 4 when playing as Sam. There is one key ring to be found in each chapter, with the exception of two key rings. In Chapter 14, Trespass, two seperate key rings can be found during this chapter, one when playing the chapter as Eddie, and the other when playing as Sam. In Chapter 22, The Fall of an Icon, two seperate key rings can be found during this chapter. They are in the same spot, but can only be found depending on the player choice made in Chapter 13, Return to the Scene of the Crime. The first key ring can be found if the player helped Sam and second key ring can be found if the player left Sam. It does not matter what has happened to Jackie in Chapter 18, Your Man with the Tattoo.
