Ninja Gaiden

• 1. Introduction

  ›

  Ninja Gaiden, the action series from the company Tecmo, is remembered first for a cruel continue screen. In the 1988 arcade original, the player's character appears chained to a table beneath a descending circular saw. Few games announce their difficulty so bluntly.

  Ryu Hayabusa, the ninja at the center of most later games, anchors the series. In Japan it was first called Ninja Ryukenden. The word gaiden in the North American title means side story in Japanese. By 2008, those side stories had shipped over 7.7 million units worldwide.

  Three questions run through the story ahead. How did a street brawler from 1988 become a cinematic platformer, and later a three-dimensional test of nerve? Why do players tie the name to extreme difficulty? And what happens to a franchise that keeps telling side stories, cancelling games and returning years later?

  In 1988, the arcade version of Ninja Gaiden sent a nameless blue ninja across the United States. A second player controlled a red ninja. The game was a beat 'em up in the style of Bad Dudes, built around street fights rather than platform jumps.

  The villain was an evil cult led by a descendant of Nostradamus. He wanted to fulfil his ancestor's prophecy that an evil king would rise in 1999. The hero moved through several regions to stop him.

  A flying neck throw and a backflip were among the player's techniques. Throwing enemies into background objects such as street lights and dumpsters produced power-ups. The ninja fought mostly with bare hands. A sword appeared only as a temporary power-up, and overhead objects served as props for stronger kicks.

  The cast of opponents was small. Five kinds of enemies filled the game, and all of them showed up in every level, though some levels added extra types.

  Home conversions followed from Ocean Software for the Amstrad CPC, Commodore 64, Amiga, Atari ST and ZX Spectrum. Europe knew these versions as Shadow Warriors. The Amiga edition kept nearly all the graphics, the two-player cooperative mode and the introduction.

  Hi Tech Expressions made an MS-DOS port for North America, where the title stayed Ninja Gaiden. It had stripped-down mechanics and a palette of only 16 colours. The game also reached the Atari Lynx handheld.

  Decades later, an emulated copy of the arcade game appeared as a bonus in an updated Xbox release called Ninja Gaiden Black. Nintendo's Wii Virtual Console offered it as a download too.

• 3. The NES Trilogy

  ›

  On the 9th of December 1988, Japan received the first Ninja Gaiden for the Nintendo Entertainment System. The United States followed in March 1989, and Europe on the 15th of August 1991. Its story begins when Ryu Hayabusa finds a letter from his recently missing father, Ken, telling him to travel to America and meet an archaeologist, Dr. Smith.

  Dr. Smith explains that Ken and the doctor hid two statues that could end the world if they were brought together. Ryu ends up in South America. There he fights Jaquio, an evil cult leader who wants to revive an ancient demon called Jashin, and who is blamed for the attack on Ken.

  The arcade game shares little story with this one, yet a few traces survived. The first stage loosely adapts the arcade's first stage, and the opening cutscene faintly echoes the arcade introduction. Both games include lookalikes of Jason Voorhees. The arcade's final boss also faintly resembles the NES villain Bloody Malth.

  Cutscenes gave the NES game its reputation. G4's X-Play credited it as the first console game to tell its story through cinematic scenes. It also introduced the boomerang-like Windmill Shuriken and the magical Ninja Arts, which spend collected power-ups. Players praised the tight action-platform play and the catchy music.

  Ninja Gaiden II: The Dark Sword of Chaos brought a new enemy named Ashtar, Emperor of Chaos and master to Jaquio. Ryu must rescue Irene Lew, a former CIA agent, and destroy the Dark Sword. That weapon was forged from a bone of the demon, just as the Dragon Sword is forged from a dragon's fang. Jaquio turns out to have been reborn.

  Spirit Clones debuted here. These invincible copies of Ryu mimic his movements and fight beside him. Ryu also learned to scale walls without jumping upward over and over. GameTek ported the game to IBM PC compatibles and the Amiga for North America, adding the ability to save a player's exact position. The IBM PC version used 256-color VGA graphics.

  A sword extension power-up, new surfaces to hang from and automatically scrolling areas rounded out the changes. The third game reached the Atari Lynx with all its content intact. Meanwhile, Hudson Soft made a PC Engine port of the first game with enhanced graphics, reworked music and rebalanced difficulty, and Tiger Electronics released an LCD handheld version in 1988 that also had a sequel.

  Sega, working under license from Tecmo, developed three Ninja Gaiden games but released only two. One was for the Master System and the other for the Game Gear. Both carried the Ninja Gaiden name, the first time a series game did so in Japan and Europe.

  The Game Gear title arrived in 1991 in Japan, North America and Europe. It felt unlike any other entry. The screen was smaller, the sprites bigger and the pace slower. Where the NES and Master System games leaned on platforming, this one was a more linear side-scroller.

  The Master System game reached Europe, Australia and Brazil in 1992. Its mechanics resemble the NES games, but Ryu bounces off walls instead of clinging to them, as he later would in the 3D games. Its storyline, characters and scenarios were entirely new.

  The third Sega project, a Mega Drive and Genesis version, was in development in 1992 and never shipped. Magazines reviewed it anyway. It was planned as a belt-scroll beat 'em up like the arcade game rather than a platformer. Ryu would have traveled to the United States to hunt two rogue sibling ninjas, Jin and Rika, who stole the Secret Scrolls of the Huma.

  A beta build later leaked online as a ROM image. It holds seven stages with cutscenes and bosses, but also bugs, odd controls, unfinished levels and cutscenes that skip before they finish. Its opening and stage names are in Japanese, while the other cutscenes were translated into English. Casino stages and hockey-mask-wearing punks recall the arcade game.

  Around 60 people worked on a PlayStation 2 Ninja Gaiden, planned for release in 2000 alongside the console's United States launch. That game was cancelled too. The next version to reach players would come from a different team entirely.

  ›

  Tecmo's own Game Boy entry was Ninja Gaiden Shadow. It began as a licensed edit of a proposed Game Boy port of Natsume's Shadow of the Ninja, and it serves as a prequel to the original game.

  In 2004, Japan got Ninja Gaiden X on mobile phones. This short single act is a prequel to the first NES title and keeps the elements of the classic Nintendo trilogy.

  Ninja Gaiden: Dragon Sword arrived in March 2008 on the Nintendo DS. Players held the system sideways and controlled the action with the stylus. The view was diagonal and top-down, with 3D graphics. The story is set six months after the 2004 game, and Momiji is a new playable female ninja.

  A Japanese release in 2012 for Android and iOS, 100 Man'nin no Ninja Gaiden, played much like Dragon Sword but added card collecting and trading. A North American release under the title Ninja Gaiden Clans was announced that year and then cancelled.

  Yaiba: Ninja Gaiden Z came out in 2014 for PlayStation 3, Xbox 360 and Microsoft Windows. It follows a ninja named Yaiba Kamikaze. Reviews were mixed, with many magazines and websites criticizing the repetitive gameplay, the difficulty and the level design. A prequel comic from Dark Horse Comics, written by Tim Seeley and Josh Emmons, explains how his sword came to be called Heartless.

• 6. The Xbox Revival

  ›

  After several quiet years, Ninja Gaiden returned in 2004 on the Xbox. Team Ninja, the makers of Dead or Alive, spent five years on it under director Tomonobu Itagaki. It sold well and earned a 94% score on Metacritic. Electronic Gaming Monthly named it Best Xbox game of the year.

  The game is a standalone prequel to the NES series. It takes place in the same universe as the Dead or Alive fighting games, called Earth-9604. Ryu Hayabusa sets out to recover the Dark Dragon Blade from evil hands after most of his clan has been wiped out. Later sequels bring in Ayane, Momiji and Rachel as supporting characters.

  According to Eurogamer, the Strider arcade games were a vital influence on this modern incarnation. Like the NES original, the Xbox game is known for its high difficulty.

  An updated version with new content, modes and features followed the next year as Ninja Gaiden Black. Ninja Gaiden Sigma, directed by Yosuke Hayashi, reached the PlayStation 3 on the 3rd of July 2007. It reworked the graphics to high definition and made Rachel a playable character.

  In 2012, Ninja Gaiden Sigma Plus was a launch title for the PlayStation Vita. It added new costumes for the playable characters, touch controls, stronger ninpo attacks and a new trophy list.

  Microsoft Game Studios published Ninja Gaiden II in 2008 for the Xbox 360, set one year after the 2004 game. It offered four difficulty levels, a regenerating health bar, upgraded graphics and better enemy AI. Ninja Gaiden Sigma 2 came to the PlayStation 3, and Ninja Gaiden Sigma 2 Plus reached the Vita in 2013.

  On the 23rd of January 2025, Ninja Gaiden II Black was announced and released at once. This Unreal Engine 5 remaster combines features from the original game and Sigma 2 for PlayStation 5, Windows and Xbox Series X/S.

• 7. After Itagaki

  ›

  Tomonobu Itagaki left the series shortly after Ninja Gaiden II. Tecmo Koei still owned the franchise, though, and planned another game with a newly restructured Team Ninja. The title was revealed as Ninja Gaiden III at the Tokyo Game Show 2010.

  Yosuke Hayashi, the new director, promised new directions, including a sense of resistance when cutting through enemies. At E3 2011 the game was shown as Ninja Gaiden 3. Dismemberment was removed. A slide replaced the roll, and a kunai climb let Ryu scale certain walls.

  Tecmo Koei released it on the 20th of March 2012 for the PlayStation 3 and Xbox 360. An expanded version, Ninja Gaiden 3: Razor's Edge, followed on the 18th of November that year for the Wii U. In early 2013 it came to the PlayStation 3 and Xbox 360 as well.

  In February 2020, Nioh 2 director Fumihiko Yasuda said several Team Ninja members wanted to make a new game. He "hoped to deliver some good news one day" and mentioned a female spin-off featuring Kasumi, Ayane, Momiji and Rachel. In 2024, Wo Long: Fallen Dynasty director Masakazu Hirayama said there were "no plans at the moment" to revisit Ninja Gaiden.

  Then, in January 2025, Microsoft Gaming's Xbox Developer Direct presentation announced a new modern entry with Hirayama as co-director. Team Ninja and PlatinumGames made it jointly. Xbox Game Studios published Ninja Gaiden 4 on the 21st of October 2025 for PlayStation 5, Windows and Xbox Series X/S.

  In 1995, Ninja Gaiden Trilogy gathered the three NES games on the Super Nintendo. They were straight ports, not tuned for the new hardware. Passwords were added and the cinematic sequences were redrawn. The third game followed the Japanese version, with infinite continues and lower damage from enemy attacks. The ports have no closing credits.

  Nintendo's "Family Friendly" censorship policy of the time shaped other changes. A pool of blood turned from red to green, and pentagrams were removed. Parallax scrolling vanished from some backgrounds, such as stage 2-1 of the third game, and a few music tracks were dropped. Some script censorship was actually loosened: Jaquio's "Argh! He's awake" became "Damn, he's awake". The same trilogy is an unlockable bonus in the 2004 Xbox game.

  On the 10th of June 2021, Ninja Gaiden: Master Collection collected Ninja Gaiden Sigma, Sigma 2 and Ninja Gaiden 3: Razor's Edge. It came out on Windows through Steam, Nintendo Switch, PlayStation 4 and Xbox One. It was the first time the Sigma games reached Nintendo and Xbox platforms.

  Outside the main games, an anime OVA called Ninja Ryukenden appeared only in Japan in 1991. The NES game also received a novelization in the Worlds of Power series, which adapted other current Nintendo games.

  Ryu, Rachel, Momiji, Irene Lew and Muramasa appear in the Dead or Alive games, with the first three playable. Ryu and Momiji make cameos in Dynasty Warriors: Strikeforce. Ryu, Rachel and Momiji are playable in Warriors Orochi 3, where they help the other warriors from another dimension. Ryu appears in Warriors All-Stars and as a playable character in Warriors Orochi 4 Ultimate.

  In Nioh 2, presumed ancestors of Ryu named Jin and Ren Hayabusa appear as secret bosses, and Ryu himself arrives later in a patch. Halo 3 hides an armor set called Hayabusa behind collecting every hidden skull in campaign mode. Reaching 1000 gamerscore also earns an unusable replica of Ryu's Dragon Sword. Super Swing Golf: Season 2 offers "Hayabusa Ninja" as a costume for Max.
