Harrier Attack is a classic action game that follows the story of an elite special forces operative, codenamed Harrier, who must infiltrate enemy territory to gather vital intelligence. The player takes on the role of Harrier, navigating through a series of challenging levels set in various locations around the world.
Gameplay involves controlling Harrier as he moves left and right across the screen, avoiding obstacles and enemy fire while simultaneously firing his machine gun at targets. The goal is to complete each level without running out of health, which is indicated by a bar on the top of the screen. As players progress through the game, the levels become increasingly difficult, with more enemies and hazards appearing on screen.
