Onimusha: Warlords

Onimusha: Warlords, released in Japan as Onimusha (鬼武者), is the first action-adventure video game of the series, released first for the PlayStation 2 in 2001. Onimusha was originally going to be for the PlayStation, but since the release of the PlayStation 2 (the game was about 50% done at that time) it was moved to the newer console. Later it went through many changes and was released as Genma Onimusha for the Xbox in 2003. The game was also ported to Windows as Onimusha: Warlords, although this version was only released in Asia.

Gameplay in the game is similar to that in Capcom's other action-adventure series,, but with emphasis on close-range combat. The game also uses an orb-based power-up system similar to the Capcom's series.

The game features samurai Samanosuke Akechi (modeled after actor Takeshi Kaneshiro), determined to save Princess Yuki (雪姫) of the Saito clan and defeat Oda Nobunaga, resurrected after signing a pact with demons. The game also features Kaede, a female ninja who provides Samanosuke with help. They both travel throughout all of Inabayama Castle where they search for clues of Princess Yuki's whereabouts, find special weapons, and solve various puzzles.
