I played this at least 15 years ago on a Windows PC, installed from CDs. The protagonist is a black woman who is a police officer in a large city. I remember some of the early bits were tutorials for how to arrest suspects, and a driving section that included having to accelerate to a particular speed, and then decelerate to hit a particular zone.
The gameplay was third-person 3D graphics, more overhead than over-the-shoulder. There were both guns and melee combat, as well as the ability to use vehicles. If you got injured, you started leaving a blood trail that enemies could follow.
Early on, you're dealing with regular crooks and gang members, but later in the game, you encounter "Men in Black" enemies wielding sci-fi weapons and able to take inhuman amounts of punishment and late parts of the game, if I recall correctly, have you battling demons summoned by one of the gang leaders.
I don't think I actually finished the game, but I have a vague memory of reading a bit about it from a strategy guide, and learning that the final boss refers to the protagonist as "a Nubian warrior" to emphasize his prejudices.
