Dynasty Warriors and Samurai Warriors join forces in this anachronistic crossover release by Japanese developer Omega Force. A total of 77 combatants are available to play as or against, brought together in one time period by the powerful Serpent King Orochi in an arrogant attempt to determine the mightiest warrior. The heroes from Ancient China and Feudal Japan include Yoshimoto Imagawa, Goemon Ishikawa, Lu Bu, Nobunaga Oda, Cao Cao, and other legends. A new team battle system has players creating custom three-man squads and controlling their choice of characters in melee combat.
While one character actively participates in battle, the remaining two will recover from damage until players decide to switch control at any time during battle. Four original storylines are available to follow as players ultimately attempt to defeat the evil Orochi. After defeating armies within the campaign, players can revisit scenarios in the "Free" mode to build their favorite character's stats and abilities. Warriors Orochi also introduces a "Weapon Fusion System" that combines the attributes from different weapons for more powerful iterations. Over 300 artifacts from both Dynasty Warriors and Samurai Warriors can be collected and viewed within the in-game gallery.
