Type of Game: First Person Shooter

We see this property sort of like the new game, Payday: The Heist. What would separate this game from that one though is the ability to have full scale street gun battles, as seen in the awesome film.  Add in an engrossing storyline, with the option to play either the cop or the robber, and you have a hit on your hands. Now how come this game hasn’t already been made?
