Ninja Warriors (also known as The Ninja Warriors Again in Japan and Ninja Warriors: The New Generation in Europe) is a beat 'em up video game developed by Natsume and released by Taito Corporation for the Super Nintendo Entertainment System in 1994. The game is loosely based on the 1987 Taito's in-house arcade game The Ninja Warriors, but features a highly altered gameplay. Ninja Warriors is a single-player, side-scrolling beat 'em up. The player can pick from the strong Ninja, the balanced Kunoichi, or the fast Kamaitachi. Each character is played in a different way and has its own set of moves: a combination of ground attacks, jumping attacks, and throws. They can also assume a defensive posture and charge a power bar that allows them to unleash a blast that attacks all enemies. The player will advance through nine levels fighting large numbers of enemies, often being stopped from advancing until all enemies on the screen are defeated. Enemies can approach the player from the left and right sides of the screen and have the ability to move off screen, while the player cannot. At the end of each level, as common in beat 'em up games, the player must defeat a boss. The North American and European versions of the game was censored (changes made to the original Japanese version include removal of the female ninja enemies and green color of blood).The European version, published by Titus Software, is also noticeably slower and easier than the other two.
