About the game

Shadow of the Ninja, originally released in Japan as Yami no Shigotonin Kage and later released in Europe and Australia as Blue Shadow, is a 1990 hack and slash platform game developed and published by Natsume for the Nintendo Entertainment System. The game revolves around a pair of ninja sent to assassinate a dictator in a futuristic version of New York City. A port was planned for the Game Boy, but was released in a rebranded form as Ninja Gaiden Shadow. A remake, Shadow of the Ninja: Reborn, was released in 2024.

Our verdict: Play it

Shadow of the Ninja came out in December 1990, with Emperor Garuda ruling a 2029 New York City and only two ninjas sent to deal with it. Mike, Sean and Joe played it right after Ninja Crusaders. We liked it more than we expected. The trouble is that it is our fourth ninja game in a stretch.

What works

  • Platforming that is part of the fight. You hang from the underside of platforms and monkey-bar across, and levels scroll both ways with moving platforms and pitfalls. We jumped between attacks and ducked under enemies to reach them, so movement never felt like just getting from A to B.
  • One-on-one duels. Enemies came from the right, so you clear what is ahead before moving on. Most of them shoot, and learning how often and where is the real skill. We liked the humanoid enemies and bosses better than the mecha ones.
  • Generous health. There is a bar, not one-hit deaths, so a few times we tanked damage and walked past the flying robots in stage two.
  • Short stages. Five levels split into about 14 stages: speedrunnable if you are good, slow and methodical if you are not.
  • A good toolkit. Katana, throwing stars, the Kusari Gama (chain and sickle), a bomb, and a screen-clearing attack that costs a chunk of health. A Reddit post says ninjas really did use hand grenades, so the game is lore accurate.

What got in the way

  • The monkey bars cost us. It is hard to tell which ledges grab, and hanging can leave you in a shot's path.
  • Boss health. Some bosses took many hits before the bar moved, and the last boss took minutes with no visible damage.
  • Hitboxes taller than they look, which wrecked our attempts to jump over fights.
  • Two-player shares continues and items but not health, so a player dying constantly drags both down.
  • No instructions for the screen-clearing attack in the manual.

Beyond the game

A Game Boy version was reworked into Ninja Gaiden Shadow, which keeps the hanging and enemy types. Shadow of the Ninja Reborn arrived in 2024 and looks like a Metal Slug cousin, though we hear it is very hard. Against Ninja Crusaders we gave this one the edge for a guy with a boomerang and a look that fits 1990.

The bottom line

Play it. It was the most fun we have had with a ninja game on the show, but no vote put it on the Essential Games List. Mike called it a recommend and still said no, with genre fatigue after Little Ninja Brothers, Ninja Crusaders and now this. Sean said not essential for now. Joe said it is solid and worth playing but he would not feel right voting Essential. We will see where it lands in the best of 1990 episode.
