Although each of the games in the series do not seem to follow a connected plot, the games all involve the undead forces of feudal Japanese warriors attacking the protagonists.
In the first two games, the player could play as a ninja or a Western cowboy. In the games, the player can gain powerups so that the player can change into more powerful forms, such as a samurai-like being, an armor-clad wolf, or a more traditionally-themed ninja to attack the opposing forces of the undead. Power ups in the form of different colored orbs included being able to wield one katana (red orb), a pair of katanas (blue orb), a broadsword (purple orb), or to launch an energy-based attack (yellow orb). (Note: Power up effects differed depending on which form the player used. Those listed are for the standard form.)
The third game did not have a similar premise to the previous two games, instead, it was about a ninja clan who had to stop a worldwide outbreak of the Japanese demons before the world would be engulfed in chaos.
