About WARRIORS OROCHI

Without warning, the venomous Serpent King Orochi descended from the heavens. 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.

In WARRIORS OROCHI the characters from both franchises must team-up to wage war against this new, yet powerful force. The game boasts an amazing roster of 79 playable characters, while four action-packed“crossover” storylines feature amazing team-ups and some long-awaited confrontations between characters from both series.

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.

WARRIORS OROCHI for PSP boasts the massive seamless battlefields of the console versions, and includes all 79 playable characters, plus 2-player co-op play via wireless (ad-hoc).
