 "Dogyuun" is a science fiction-themed vertically scrolling shoot 'em up game reminiscent of "Aero Fighters" and "Recca", where players assume the role of two pilots who took a part on a reconnaissance mission on planet Dino taking control of the Sylfers bomber space fighter crafts through ten stages in a revenge effort to defeat an invading alien race of metallic robots who have captured a police communication center and its inhabitants after their comrade, Kyle, was killed by one of them as the main objective.As far as vertical scrolling shooters go, the game initially appears to be very standard; Players start with a single laser beam that can be held on at close range for dealing minimal damage against enemies when not firing and other weapons can be acquired by destroying incoming carriers, ranging from homing lasers to a lightning beam, which can be distinguished by their color.If a weapon module of the same color is picked up, a 5000-point bonus is granted.
