Thunder Dragon (4th Jun. 1991, protected) — About this game

Thunder Dragon (4th Jun. 1991, protected) sends its attack helicopter through eight stages of enemy vehicles, aircraft and larger boss machines. Numbered pickups change the main armament between a broad spread, rapid Vulcan fire, a reflecting laser and napalm missiles. A separate bomb stock provides a stronger answer to heavy opposition. Bonus stars also have a practical use: collecting five brings another bomb item into play. Choosing the next numbered weapon therefore changes both the coverage of ordinary fire and how comfortably the helicopter can approach the next formation.
