Soukyugurentai is a top-down shooter using an elaborate combination of pre-rendered and real-time 3D graphics as well as 2D pixel art.
The player is given a choice to control one of the three fighter ships of the JIN-SET Corporation Self-Defense Corps, all with strangely fish-themed names - S.O.Q. 004 Swordfish, S.O.Q. 010 Mackerel,and S.O.Q. 025 Scallop. Each ship comes with a unique, upgradable weapon system - Swordfish uses an all-around average rapid fire gun, Mackerel fires a weak laser and homing missiles, while Scallop obliterates foes with a narrowly-focused rail gun and a sub-cannon that fires in a direction opposite to the ship's motion. In addition to the primary weapons each ship carries a lock-on laser, activated by holding down the fire button.

Overseas release

Sōkyūgurentai was localized as Terra Diver for release outside Japan. While it's not clear whether any overseas release actually happened, Japanese cartridges have a label with both titles and the game boots up in English as Terra Diver in overseas ST-V cabinets. The original Saturn version has a partially-complete localization as Terra Diver which is enabled when the game is booted on a non-Japanese Saturn; that translation was removed in the Otokuyō rerelease later in the same year.
