The game uses a top-down vertical scrolling view. Players guide their fighter through successive stages while dodging bullets and destroying air and ground targets. Defeated enemies drop power-ups, and some items can be combined to alter weapon behavior or strengthen attacks. Each stage ends with a boss battle that requires pattern recognition, careful positioning, and efficient movement. Progress is stage-based and becomes more demanding as enemy density increases.
