Alex Kidd in Shinobi World is a side-scrolling action game produced by Sega that was originally released for the Master System in 1990 and later re-released for the Wii Virtual Console in 2009.
Although developed in Japan, it was released exclusively for the overseas market, with the American version being produced in limited quantities. The game stars Alex Kidd in a parody version of Sega's ninja-themed action game Shinobi, where Alex Kidd fights against caricatures of many of the enemies from Shinobi. It is the final video game in the Alex Kidd franchise.
An evil creature known as Hanzo escapes after 10,000 years of confinement and kidnaps Alex Kidd's new girlfriend from planet Shinobi. After the kidnapping, Alex encounters the ghost of the ancient warrior who originally vanquished Hanzo, who explains that Hanzo intends to sacrifice Alex's girlfriend in order to conquer the world. The spirit of the ancient warrior fuses itself with Alex's body, lending Alex his strength, skills and knowledge.
Despite being part of the Alex Kidd Series, the game mechanics of Shinobi World are different from Alex Kidd in Miracle World and are much closer to the Master System version of Shinobi. Alex's basic attack is a sword slice, which can be used not only to destroy enemies, but also to open treasure chests. Inside such chests, the player can obtain items such as more health, throwing darts, a powered-up sword, extra lives, and a magic ball that will temporarily turn Alex Kidd into an invincible tornado. The throwing darts and powered-up sword will both replace the Alex's default sword until the player completes the stage or defeats a boss. Other actions that Alex Kidd can perform include a wall-to-wall jump and the ability to turn into a flying fireball after spinning around a street post, a rope or a horizontal bar.
Alex starts off each round with three hit points, but can fill out his health gauge to a maximum of six hit points. When the player has full health, all the treasure chests carrying hearts will carry extra lives in their place. When the player defeats a boss with full health, he will gain a "Perfect Bonus" after completing the round. There's also a "Secret Bonus" if the player completes an entire round without getting hit or losing life at any point.
- Alex Kidd in Shinobi World's' cartridge label is normally the regular red with black grid design, however a much rarer blue label version exists and is considered to be somewhat of a collector's item among Master System game collectors.
- In the beta version of the game, the boss of Round 1, called Kabuto in the released version of the game, had a different design. He was originally named "Mari-Oh" and was designed as a pastiche of Mario, the mascot of rival game developer Nintendo.
