Soukyugurentai is a vertical-scrolling shooter. The player picks one of three different ships - red, green or blue - each with their own pilot, fire pattern and laser web. Each ship has a standard gun and a bomb, but the most distinctive of these aspects is the laser-web: holding down the button for the standard gun will release a lock-on laser-web traditionally shaped as a cone or semicircle, which will destroy the enemies it locks onto after releasing the buttons. Each ship has two different lock-on weapons that function as web-designed laser targets. Once an enemy enters the web's range, the player can destroy the enemy or multiple enemies can be destroyed via homing lasers or multiple fireballs. The game is unusual in that, rather than using a 3:4 aspect ratio, to better suit the vertically oriented gameplay, it uses a horizontal monitor (4:3) in the style of Neo Geo vertical shooters as well as the later Radiant Silvergun and Giga Wing.

In the 2050s, the Earth's environment deteriorated significantly, even after strict limits were placed on the use of fossil fuel and the emission of carbon dioxide. As a result, many space development corporations were established and began the construction of space colonies and the terraforming of other planets in the Solar System. The largest of these companies was the Jin-Sei Corporation, headquartered in Japan and founded by the Miama family. To protect its corporate interests, the Jin-Sei Corporation established the private self-defense force JDF, also known as the Soukyugurentai. The JDF was armed with the S.O.Q. series of small general-purpose spacecraft, all of which were equipped with the No Blindspot All-range Laser System (N.A.L.S.). Throughout the course of the game, the JDF comes into conflict with various groups acting against Jin-sei, including the corporate terrorist group Small and Medium Enterprises Liberation Front, the anti-space development eco-terrorist group Little Earth, and Jin-Sei's rival corporation, the Bafu Interstellar Development Company.
