The screen scrolls horizontally as the player drives a combat jet ski across water. The objective is to survive each stage, destroy hostile units, and reach the end-of-level confrontation.

Players steer around islands, shorelines, bridges, and other hazards while firing at targets. Stages become more demanding through denser enemy formations, faster threats, and boss encounters. Two-player sessions allow both players to fight through the same route together.

Keep moving while firing continuously, but avoid traveling blindly into narrow passages or shoreline obstacles. Enemy projectiles and terrain hazards can be equally dangerous, so prioritize threats that block the route.

In two-player games, spread out when the screen allows it and focus fire on large targets. Learn boss attack patterns rather than staying directly in front of them, and preserve safe movement space for the final approach.
