Shinobi

Shinobi (忍) is a side-scrolling hack and slash video game produced by Sega, originally released for arcades on the Sega System 16 board in 1987.

Shinobi was a commercial success in arcades; it topped the monthly Japanese table arcade charts in December 1987, and became a blockbuster arcade hit in the United States, where it was the highest-grossing conversion kit of 1988 and one of the top five conversion kits of 1989. It was adapted by Sega to its Master System game console, followed by conversions to the NES, PC Engine, and home computers. It was re-released as downloadable emulated versions of the original arcade game for the Wii and Xbox 360. The arcade game joined the Nintendo Switch in January 2020 through the Sega Ages series. Shinobi's success inspired various sequels and spin-offs of the series.

Story
Shinobi is about a ninja named Joe Musashi who has to stop a criminal organization called "Zeed" who are kidnapping the children of the Oboro clan. Through five missions of increasing difficulty, Musashi must make his way to Zeed's headquarters and free all the hostages before confronting Zeed's leaders known as "Ring of Five", which are formidable enemies on their own.
