Iridion II video review. Classic Game Room presents a CGRundertow video review of Iridion II from Shin'en and Majesco Games for the Game Boy Advance. Iridion II is a sequel to Iridion 3D, an early GBA game with a great 3D engine and less great gameplay. For Iridion II, however, the team at Shin'en took a more old-school approach. This is a more traditional 2D space shooter, trading awesome tech for awesome gameplay. This video review features video gameplay footage of Iridion II for the Game Boy Advance and audio commentary from Classic Game Room's Derek.
