TAS Genesis The Revenge of Shinobi by CoolHandMike in 12:

This is a tool-assisted speedrun. For more information, see TAS originally published on 2020-03-27. In The Revenge of Shinobi, the prequel to Shinobi III, you play as a ninja (what else?) who is capable of destroying an entire army of other ninjas, soldiers, and Hollywood characters. The fast attack animation of the ninja (one of which throws fireballs everywhere) makes up for his lack of speed. In this run, CoolHandMike beats seconds thanks to lots of new glitches and a new ceiling clip.
