Ninja Gaiden Trilogy is a compilation of the three games in the series previously released for the NES:
- Ninja Gaiden
- Ninja Gaiden II: The Dark Sword of Chaos
- Ninja Gaiden III: The Ancient Ship of Doom
All three games tell the story of ninja Ryu Hayabusa through alternating cinematic cutscenes and levels of 2D side-scrolling action. The graphics and sound are essentially the same as in the originals, but enhanced for the SNES.
