Samurai Warriors: Spirit of Sanada (戦国無双 ～真田丸～, Sengoku Musou ~Sanadamaru~) is a spin-off Samurai Warriors 4: Empires game centering on the exploits of the Sanada clan. Its Japanese release coincided with the similarly named 2016 NHK Taiga drama Sanadamaru; this game even reuses the same Kou Shibusawa supervised 3D maps that are used in the drama and Nobunaga's Ambition: Sphere of Influence.
