The "Police Car Pack" mod reveals special cars in the game that cops drive and chase street racers. They are all free from the racing dealer.
I definitely include FrostyModManager v1.0.4.2 in the kit to make it easier to install the Police Car Pack in NFS Payback. Everything is done in a couple of clicks.
Now a street racer can show himself in the shoes of a cop, in their cars. This is called a friend among strangers in the game Payback.
