Shadow Warriors (or Ninja Gaiden Shadow, depending on where you got it) is the Game Boy's take on Ryu Hayabusa's ninja action—and honestly, it's way better than it has any right to be. You’re still slashing through enemies with that satisfying little sword swipe, but now you’re doing it on a tiny screen while dodging bats and jumping over bottomless pits. Classic stuff.

Emperor Garuda’s up to no good (shocking, I know), so you’ll bounce between rooftops, caves, and some seriously mean platforming sections. The controls feel tight for a Game Boy game, though some of those jumps will still make you grit your teeth. And yeah, the music’s got that crunchy 8-bit charm—you’ll be humming the stage 1 theme for days.

It’s not as deep as the NES games, but for a portable ninja fix? Still holds up.
