In this game, the player assumed the role of a Los Angeles police officer fighting rioters. In each level, the player would move toward the top of the screen avoiding or shooting the rioters, who would either, lob grenades if at a distance, or beat your character to the pavement with clubs if in melee range.
At the end of each level, a procession of gang members (usually with a single shirt color, marching in formation) would stream down from the top of the screen. After killing all of these gang members, a single gang member, the boss, would move randomly around the screen with a woman next to him. This functioned a bit like a sharpshooting competition, as shooting the woman would cause the player to lose points, while successfully shooting only the ganger would cause her to "take the arm" of your character.
As the levels progress, the gangers become more frequent and the player will begin to see cars placed perpendicular to the street, acting as roadblocks.
