When Ryu dies for the third time of the first chapter, you will be asked: "Do you wish to abandon the way of the Ninja?", choosing "Yes" results in the game asking if you're sure, choosing "Yes" again, will result in the game asking one final time: "Are you truly sure?". Ninja Dog is a hidden difficulty of the game, and is unlocked by dying three times on the first chapter of the game, enemy encounters are the same as Normal, but you are given additional items and weaker enemies for an easier experience, the damage you inflict is also increased. You must complete your task without fail. Don't be overconfident, just do what I say and perform your duties as competently as you can. I will support you in every way that I can. Oh well, we have no choice but to proceed. It seems I have greatly overestimated you. Or should I say, young Ninja Ryu Hayabusa. Ninja Gaiden Black features 5 settings of difficulty, these include Ninja Dog, Normal, Hard, Very Hard, and Master Ninja. Every five missions were connected to a specific section of Mission Mode. The key additional feature of Black was Mission Mode, it included 45 standalone missions and five linked missions that focused on combat in different arenas.


The game features several new in-game cut scenes, and uses Hurricane Pack 1 technique more frequently on Hard difficulty and above, forcing players to find other ways to overcome the foes. Its key additional feature is Mission Mode which sets up various short standalone scenarios for players to overcome.

Ninja Gaiden Black is a reworked compilation of Ninja Gaiden and the two Hurricane Packs.
