The Ninja Warriors for SNES by Taito, 1994 release, developed by Natsume. Because the yin to farming roleplaying games is the yang of Ninja Cyborg Assassin games.
Ninja Warriors is a bit of an interesting story - the original arcade featured 3 contiguous monitors, much like Taito's other arcade setup for the original Darius. This gave you a long horizontal expanse of a playfield - it looked and felt strange, but by virtue of that it felt cool and different. Just like a kid with a big playground! And of course, something that couldn't be properly replicated at home.
We never saw a domestic release of the original Ninja Warriors in the States, so when a console-only sequel was developed, they just used the first game's name (besides, "The Ninja Warriors Again" sounds strange, for a number of reasons!) At any rate, the game got a graphical upgrade thanks to the SNES' beefier processor, though of course the 3-screen setup was not a possibility.
The game involved your choice of 3 different cyborg ninjas - agile and weaker, lumbering and more durable, and of course the in-between "average" character. The gimmick here was that as your on-screen character took damage, you'd slowly see visual damage progressively shown on your character Terminator-style (especially in the case of the blonde female ninja, who unlike the other two did not have a prominent mechanical exoskeleton visible.)
As for the game itself, it was a very standard formula. Walk to the right, attack enemies, dodge projectiles. Charge up a super-attack, maul bosses, and so on and so forth. Very similar to a game like Bad Dudes, where movement is restricted to the horizontal plane with the occasional platforms to provide some vertical play. In a beat-em-up world dominated by the likes of Final Fight, TMNT and X-Men, where gameplay would take place in pseudo-orthographic space (with vertical play as well as horizontal), this felt extremely limiting and therefore not as enjoyable.
Still, the game sticks out to me because - it was gorgeous! I was always a sucker for games with these themes - military and cybernetics. When they did it right in 16-Bit, it looked incredible. Though this game was fairly light on substance, at the time that I rented it I was in love with it's aesthetic. Overall a forgettable experience, but even now it's fun to look at and play through for some mindless button-mashing and soldier-slashing.
