The game employs a classic system featuring a main shot, power-ups, and a screen-clearing bomb. Players can change their attack type by collecting lettered power-ups, such as the Spread Shot (W) and the powerful Laser (L). Its signature feature is the ability to collect auxiliary drones called "Options." These Options not only provide additional flanking firepower but can also change their formation depending on how they are collected.
For a 1989 title, the graphics were top-tier, featuring rich, dynamic background elements like crumbling terrain and giant mechanical gears. The game has a steep difficulty curve, with cunning enemy AI that will often ambush you by suddenly flying in from the rear or sides of the screen. The boss battles are especially intense; the massive mechanical bosses and their main cannons create a strong sense of visual pressure, demanding precise control and a high degree of pattern memorization from the player.
