Ninja Ryūkenden is a side scrolling action game by Hudson Soft and based on the arcade game of the same name released by Tecmo in 1988 (it is rather a port of the Famicom game, see the info section). The player controls Ryu Hayabusa, a fearless ninja on a quest of revenge. His father was killed by a mysterious ninja during a fierce duel. After reading a note left by his father, Ryu travels to the United States to meet Dr. Walter Smith, one of his father's friend. But he soon gets head to head with a young girl who hands him a weird looking statue before disappearing. The complex plot of the game unfolds over no less than six acts (with a total of nearly twenty stages) and Ryu will finally find out what happened to his father and who hides behind his disappearance. Ryu Hayabusa is equipped with a sword which he can use at lightning-speed to slash his enemies to bits. He also has the incredible ability to wall-jump and to climb vertical surfaces. Finally, Ryu can use his spiritual energy to augment his powers and trigger powerful special attacks such as mystic shurikens or the ability to shoot flames. Various energy forms scattered around some of the levels reward Ryu with spiritual energy. They are often in the shape of burning flames but they also come in various forms such as insects or small animals.

Compilation of the three games in the Ninja Gaiden series, which were originally released on the NES.

Now the adventure and thrill of this fast-paced, action-packed coin-op hit is placed in your hands! Kick, punch, and master the special Ninjutsu techniques as you battle your way through four of the nastiest neighborhoods known to man.

This is the PC conversion of the second installment of the successful arcade Ninja Gaiden series. The game is a fairly simple action-oriented, side scroller.

This time, under the leadership of "Ashtar" the dark lord who controlled the Jaquio and plots to rule the world.

Ninja Gaiden III: The Ancient Ship of Doom is a side-scrolling platform game in which the player controls the player character Ryu Hayabusa as he investigates the events behind Irene Lew's death. In the game, Ryu can jump, hang, and climb up and down walls with the control pad; pressing the jump button while holding the control pad the direction away from the wall causes Ryu to spring off the wall. Ryu is also able to attack enemies with secondary weapons while on a wall by pressing the attack button. A new feature introduced in Ninja Gaiden III is the ability for Ryu to hang overhead from pipes or ivy; he can swing up on top or drop from them, and as with walls, he can only attack enemies while hanging with secondary weapons.

Ninja Gaiden Shadow is an Action game, developed by Natsume and published by Tecmo, which was released in Japan in 1991.

A lazily produced reissuing of three great NES classics in one cartridge, Ninja Gaiden Trilogy includes Ninja Gaiden, Ninja Gaiden II: The Dark Sword of Chaos and Ninja Gaiden III. Each game remains faithful to its corresponding original in terms of gameplay, but the graphics have barely been updated (there are more colors and no flickering), the lightning in level 3-1 of the second game is missing and the backgrounds for the desert level in game three are totally non-scrolling. Passwords are a welcome addition, but the controls (B for attacking and A for jumping) are awkward and cannot be reconfigured. The most inexcusable disappointment is that the highly memorable music has been rearranged and otherwise altered for the worse. To see how a compilation of older games should be done, check out Super Mario All-Stars.

Ryu, the Dragon Ninja, travels the world to defeat evil wherever he finds it.
