Play Blue Shadow :Shadow of the Ninja Online

Game Overview

Blue Shadow: Shadow of the Ninja (or Ninja Ryūkenden if you're going by its Japanese name) is one of those NES games that somehow slipped under the radar but absolutely shouldn't have. You pick between two ninjas—Hayate or Kaede—and slash your way through this grim, neon-lit future where everything wants to kill you. The first level throws you right into it: dodging sniper fire, swinging from pipes, and realizing too late that some platforms crumble under your feet.

What really sticks with me is the atmosphere. The soundtrack's all moody synths and driving basslines, like someone fused a cyberpunk movie with an '80s action flick. And yeah, the co-op mode is a blast—there's something deeply satisfying about coordinating shuriken throws with a friend while some mechanized boss fills half the screen.

It's tough but fair, the kind of game where you'll curse a cheap death one minute and feel like a ninja god the next when you finally nail that perfect jump-kick combo. If you've ever wondered what Ninja Gaiden might've felt like with a bit more grit and a killer two-player mode, here's your answer.
