Iridion 3D

Iridion 3D was among the titles that accompanied the Game Boy Advance's launch, and its main job was to show off what the new hardware could do. It's an on-rails shmup in which the player pilots a fighter craft flying forward through space corridors and planetary surfaces, collecting weapon upgrades and facing waves of enemies as well as end-of-level bosses. Although the GBA has no real 3D acceleration, the game uses sprite scaling and rotation to create a convincing sense of depth and fast movement through space, which was a genuinely unusual sight on a handheld in 2001.

This visual trick was one of the main draws at launch – it showed that the console could handle effects reminiscent of the Super Nintendo's Mode 7, only in an even more dynamic form, and many reviewers picked it out specifically to demonstrate the new handheld's graphical capabilities. The sound design fleshes out the sci-fi atmosphere with electronic tones and reinforces the feeling of flying at high speed through space filled with enemy ships and laser fire. The gameplay itself is straightforward – it's about reflexes, dodging, and timely powerup collection, with no complicated mechanics on top, which makes the game easily accessible even to players who otherwise don't play the shmup genre.

At the time, reviewers mainly praised the technical side and the graphical flair, but criticized the short length, the high difficulty, and the lack of a way to save a game in progress, which really hurt in a demanding shmup and forced players to always start from the beginning. Even so, as a launch title, Iridion 3D earned a reputation as one of the technically most ambitious early GBA releases and helped showcase the new console's potential even before larger titles arrived for it. Today it's more of a short but still visually functional showcase of how developers managed to squeeze surprising graphical effects, impressive for their time, out of limited hardware, and for collectors it remains an interesting item from the GBA's first months of existence.
