Nemesis '90 Kai is a enhanced port/remake of Nemesis 2 exclusive for the Sharp X68000. It was developed by SPS and published by Konami, and released on November 12, 1993 in Japan.


The game follows the same plot and general stage layout of the original, although 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.
