This is a solidly performing bullet hell. It has some cool 3D graphics, and it has a not totally awful rotation mechanic. And the cabinet art was this absolutely awesome vector art of the three ships, really above average for promo art. Zero Gunner 2 seems to have gotten a lot more love than Zero Gunner 1 for some reason.
