Hack and Slash from the Onimusha lineage with Sony's budget behind it, really high production values for a PS2 game.
The story is ok ish and the gameplay while not having too many combos it's very responsive and has an addictive samurai special abillity.
However I think the boss fights makes this very impressive, the Phoenix and the final boss are some of the best you can find in this type of game at the time.
