Ninja Gaiden is a classic action NES title known for its difficulty, starring famous ninja Ryu Hayabusa as its main protagonist. Ryu has just learned that his father has recently gone missing after being defeated in a dual against his rival. He must now take up his sword and avenge his father, all the while encountering government conspiracies and supernatural events.

In this run, a group of authors decide to eschew the usual ninja methods of killing anything that wants to hurt you and go for a pacifist run, only killing when necessary to progress. To accomplish this, the RNG was heavily manipulated and glitches were abused to skip as many fights as possible and reduce the number of enemies encountered. For more information, you can read the authors' notes here.

Watch this run being played back on a real console.
