Information Global Service (IGS) was a Japanese publisher that released several notable titles for the PC Engine (TurboGrafx-16) and Game Boy. Their portfolio includes shoot 'em ups like Cyber Core, Violent Soldier, and Sinistron, as well as puzzle and action games such as Tricky Kick, Astro Rabby, and Sindibad: Chitei no Dai Makyuu.
Operating during the transition of the 8-bit and 16-bit console eras, the company collaborated with external developers to build a diverse software library. In 1990, the publisher released
Cyber Core, a vertically scrolling shooter featuring insect-themed ship mutations, alongside
Violent Soldier (later localized in North America as
Sinistron), which distinguished itself with adjustable defensive shields. The same year saw the release of
Astro Rabby, a pocket-sized action game featuring a jumping robotic rabbit, and
World Beach Volley, which brought competitive seaside athletics to handheld players.
The company also ventured into narrative-driven genres.
Sindibad: Chitei no Dai Makyuu offered a role-playing adaptation of legendary seafaring myths, while
Tricky Kick provided tactical, grid-based puzzle gameplay. In 1991, the publisher released
Mateki Densetsu Astralius, a fantasy role-playing game notable for its classical music motifs and traditional turn-based combat. These releases collectively defined the company's brief era of active software publishing, leaving behind a cult legacy among retro gaming enthusiasts.
