This is an action game in which players assume the role of a cyborg ninja (Yaiba) as he battles zombies and searches for his rival, Ryu. Players use swords and bladed whips to kill dozens of zombies, ninjas, and boss creatures. Players can use zombie body parts as weapons (e.g., using a zombie stomach to spray bile/vomit at enemies) and dismember/decapitate them during the course of battle; large blood- splatter effects often occur. The game includes some sexual material: one scene depicts a 3D silhouette of a woman straddling a man, with accompanying dialogue (e.g., “Let's just say some parts of your anatomy didn't need any enhancement.”). Drugs are occasionally mentioned in text (e.g., “...big-timers in the drug trade, coke especially.”). The words “f**k,”“sh*t,” and “a*shole” appear in dialogue.
