Ca$h 'n Guns (second edition) Expansion: The Cop adds four new guns, new loot cards, and new unique player powers to the Ca$h 'n Guns base game. What's more, this expansion includes one element present in the original Ca$h 'n Gun$ game: role cards that place one player in the role of an undercover policeman who has infiltrated the criminal underworld. Over the course of the game, this player must try to sound the alarm before everyone has finished splitting the loot.
