, also referred to as Terra Diver, is a vertical-scrolling shoot ’em up developed by Raizing, initially launched on the ST-V arcade hardware in 1996. The game was subsequently adapted for the Sega Saturn and PlayStation consoles in 1997, with both editions released exclusively in the Japanese market.

Gameplay

Soukyugurentai is a vertically scrolling shooter where players choose from three distinct spacecraft—red, green, or blue—each piloted by unique characters and featuring specialized firing patterns alongside an exclusive laser-web lock-on mechanic. This laser-web targets enemies within range, allowing players to eliminate foes using homing lasers or a barrage of multiple fireballs. Unlike most vertical shooters that utilize a 3:4 aspect ratio, this title adopts a horizontal 4:3 display similar to games such as Radiant Silvergun and Giga Wing, enhancing the vertical shooting dynamics.

Plot

Set during the 2050s, a period marked by environmental degradation despite restrictions on fossil fuels, space development corporations have risen to construct colonies and initiate planetary terraforming. The foremost entity, Japan-based Jin-Sei Corporation founded by the Miama family, established a private military unit known as JDF—or Soukyugurentai—to safeguard its corporate interests. Equipped with S.O.Q. fighter ships featuring the No Blindspot All-range Laser System (N.A.L.S.), JDF faces off against various hostile groups including corporate terrorists from the Small and Medium Enterprises Liberation Front, eco-activists called Little Earth, and competing rival Bafu Interstellar Development Company.

Releases

Soukyu Gurentai debuted in Japanese arcades in September 1996 as a cartridge for Sega's ST-V arcade system board. Although primarily distributed within Japan, inserting this cartridge into ST-V units abroad switches the game's language to English and changes its title to Terra Diver.

A port for the Sega Saturn followed in February 1997, published by Electronic Arts. Taking advantage of the Saturn’s hardware similarities with the arcade system, this version faithfully reproduces the original gameplay while adding features such as a practice mode and compatibility with both the Multi Controller and Mission Stick peripherals. A budget re-release surfaced in December 1997, bundled with a demo version of Battle Garegga.

In December 1997, Data East launched a PlayStation adaptation titled . This edition introduced a Special Mode featuring an additional playable ship and a new final stage, along with animated cutscenes and voiced navigation support. It also accommodated DualShock analog controls. Hamster Corporation later reissued this version in May 2003 under their MajorWave budget label.

In 2005, Soukyu Gurentai was adapted for Japanese feature phones and made accessible via EZWeb, i-mode, and Yahoo! Keitai mobile platforms.

Reception

In October 1996, Game Machine ranked Terra Diver as the fifth most popular arcade game in Japan. Sōkyū Gurentai remains one of Raizing’s most acclaimed arcade releases. The Sega Saturn port earned a 92% score from Consoles + magazine.

The Saturn edition received three out of five stars from Next Generation, which described it as "enjoyable, uncomplicated entertainment" and recommended it to Saturn owners seeking an alternative to Raystorm.
