Ninja Combat

 is a 1990 side-scrolling beat 'em up video game developed by Alpha Denshi and published by SNK. It was one of the launch titles for both the Neo Geo MVS (arcade) and AES (home) systems.
Gameplay.
The journey takes the ninja heroes from an amusement park to the top of a tower. Along the way, they must survive endless attacks from the members of Kage Ichizoku and their minions. The protagonists Joe and Hayabusa use shuriken as their primary weapon, although other weapons that aid them along the way are nunchaku, maces, ratchets, battle axes, spiked clubs, and katana swords. A special somersault attack can be used to knock down a multiple enemies in a row. As an art of "ninpo kairou", a fire dragon (Joe) or lightning strike (Hayabusa) can be summoned to destroy all enemies on the screen.
The heroes die if their life force runs out or time expires. Per 1,500 points scored or they pick up a gold capsule, they earn an extra life.
Plot.
The story, set in the year "199X", follows the twin ninja warriors named Joe (ジョー) and Hayabusa (ハヤブサ, lit. "Falcon") (not to be mistaken with Joe Musashi or Ryu Hayabusa), who are waging a battle against an evil ninja clan Kage Ichizoku (影一族, lit. "Shadow Family"). Their mission is to fight their way into the enemy home fortress, the Ninja Tower (ニンジャタワー, "Ninjatawa"), which has emerged from the ocean in the center of New York City, to once and for all defeat the Shadow Family and its leader, the long thought-dead demon sorcerer Genyousai. When defeated, three of the minibosses: Musashi (ムサシ), Kagerow (カゲロウ, lit. "Mayfly") and Gembu (ゲンブ), become allies and fight alongside Joe and Hayabusa as optional player characters. If the heroes are victorious, Genyousai is destroyed and the Ninja Tower crumbles.
Release.
"Ninja Combat" was originally released in Japanese arcades on July 24, 1990. Its home version was released internationally for the Neo Geo in 1991 and for the Neo Geo CD on October 31, 1994 in Japan only. The original soundtrack for both "Ninja Combat" and "The Super Spy", along with the arranged versions by SNK Sound Team and KONNY, was published by Pony Canyon and Scitron on November 21, 1990.
"Ninja Combat" was re-released through Nintendo's Virtual Console download service in Europe and Australia on October 26, 2007, and in North America on June 2, 2008. It is also one of the five games ported to the PlayStation 2 in the game compilation "ADK Damashii" in 2008.
Reception.
"RePlay" reported "Ninja Combat" to be the second most-popular arcade game at the time. In Japan, "Game Machine" listed the game on their December 15, 1990 issue as being the eighteenth most-popular arcade game at the time. The title received mixed reception from critics since its release in arcades and other platforms. The original Neo Geo release holds a 37.50% on the video game review aggregator "GameRankings".
"AllGame"s Kyle Knight heavily criticized its overall design, unacceptable graphics, audio, controls, technical issues and cheap gameplay, stating that ""Ninja Combat" is a poorly conceived, poorly executed game." In contrast, "Electronic Gaming Monthly"s four reviewers commended the audiovisual presentation and playable characters having their own fighting style but criticized the Neo Geo AES version for using unlimited continues, short length, easy difficulty and repetitive gameplay. "Raze"s Julian Boardman also shared a similar opinion, stating that the use of unlimited continues hampered both gameplay and challenge. However, "ACE"s Tony Dillon argured with this sentiment by claiming on his review that the unlimited continue feature was a hardware design flaw on the first batch of AES systems. Dillon praised the game's audiovisual presentation, stating that "this game is fulfilling what the Neo Geo promises - a standard arcade machine for the home" but criticized its short length.
French magazine "Joystick" regarded "Ninja Combat" as one of the best beat 'em ups on consoles and comparing it with "Double Dragon" and "Final Fight", praising the audio and visuals as well as the sprite animations and controls highly but criticized the overall short length. "Superjuegos" Alberto Pascual praised the game's ability to recruit defeated minibosses as playable characters and two-player mode but felt mixed in regards to the originality on-display. "Computer and Video Games Mean Machines" compared the title with "Shadow Warriors", commending the audiovisual presentation but criticized the gameplay for being dull and boring to play, easy difficulty and short length. In a similar manner, Italian publication "Consolemania" also compared it with "Shadow Warriors", praising the graphics but criticized certain aspects of both audio and playability.
"Eurogamer"s Dan Whitehead regarded "Ninja Combat" to be a rip-off of other titles in the beat 'em up genre such as "Shinobi" and "Streets of Rage", praising the graphics and ability to recruit additional characters but criticized the collision detection, stiff animations, poor controls, lack of ideas and short length. "IGN"s Lucas M. Thomas called it "a profoundly unappealing gameplay experience," opining that "anything potentially innovative or interesting about "Ninja Combat" gets totally defeated by its terribly stiff control and overly difficult programming." "Nintendo Life"s Damien McFerran criticized the visuals for being unispired and character designs, while stating that its gameplay is not comparable to "Streets of Rage" or "Final Fight".
