An unnamed police version of the Bravado Bison pickup is due to appear in Grand Theft Auto VI, shown in an official screenshot parked mid-street in Vice City as officers apprehend a suspect nearby. It takes the form of the second-generation Bison fitted with a lightbar and what appears to be a Vice-Dale Police Department livery with a gold emblem and green striping.
