In this Afterburner-inspired Gameboy Advance launch title, a player pilots the SHN fighter through seven pseudo-3D levels. Returning to Earth from a space mission, the protagonist notices that the Iridion empire has taken over. The SHN fighter can be upgraded with five different types of weapons for varying methods of destruction. This is German developer Shin'en's first English game, however, they have prior experience, having developed sound drivers for both the GBA and GBC.
Iridion 3D takes its name from the unfinished Amiga 2D shooter Iridion made by Shin'en's former self, Amiga demo group Abyss. The title was later transferred to Gameboy Color, but was never finished on that platform either.
