Siren City is a game for the Commodore 64 which involves the player taking the role of an American "Cop Car" patrolling the streets of dangerous Siren City.

Grand Theft Auto developer Steve Hammond discusses Siren City as inspiration for Grand Theft Auto as a "top-down car game with cops".

Starting as a rookie driving through a maze of Skyscrapers and seemingly peaceful streets, the player's job is to keep law & order, however the player encounters many of the toughest criminals in the city.

The player undertakes a number of missions, ending after either a set objective achieved or a fixed time duration.
