Without warning, the evil Serpent King Orochi descended from the skies above. Using his unworldly powers to shatter time and space, Orochi kidnapped the strongest, wisest and most courageous warriors from Ancient China and Feudal Japan in a scheme to test his might against the heroes of these ages.

Most of the great armies of these two periods would succumb to the might of Orochi. Yet powerful warriors remain and are ready to continue the fight. Now, the greatest showdown in history is about to take place.

Warriors Orochi boasts an amazing roster of 77 playable characters from both the Dynasty Warriors and Samurai Warriors franchises, while four action- packed "crossover" storylines unveil events where characters from either series are pitted against one another. The game's new "Team Battle System" and "Weapon Fusion" push Tactical Action to a whole new level. For the first time in KOEI's Tactical Action games, players can create their own three-person tag team. At any given time, one warrior will be engaged in battle, while the other two are recuperating; restoring their Life Meters and Musou Gauges. Every character is categorized according to offensive ability, and with new fighting techniques, it's up to the player to find the most lethal combination of warriors. "Weapon Fusion" lets players combine the attributes from different weapons for more devastating results.
