Nemesis '90 Kai is a enhanced port/remake of Nemesis 2 for the Sharp X68000, developed by SPS and published by Konami. It was unfortunately never ported to any other system.
The game follows the same plot and general stage layout of the original, though with many notable enhancements and additions:
- Fully redrawn 16-bit graphics, on par with the SNES version of Gradius III;
- Smooth scrolling and better controls due to the more powerful hardware;
- Fully remixed soundtrack as well as new sound effects;
- A handful of new bosses exclusive to this version, which replace the boss rematches of the original;
- Two new stages: an asteroid field and a waterfall area;
