Players move a base left and right along the bottom of the screen and fire upward to eliminate descending alien formations. The collection includes arcade-style ports and Virtual Boy-enhanced 3D versions, along with modes such as score attack and time attack. Progress is based on clearing waves and maximizing points, while enemy formations become more dangerous as they move lower and change rhythm with each surviving group.
Focus on enemies closest to the bottom line first to prevent the formation from reaching an unsafe height. Shoot in controlled bursts to keep accuracy high. In score attack, prioritize efficient hits on high-value targets; in time attack, aim for fast wave clears and avoid wasted movement. Adjust quickly to the stereoscopic depth so you do not misjudge enemy position.
