Tenchu Shinobi Gaisen

Tenchu: Shinobi Gaisen (Rittai Ninja Katsugeki Tenchu) is an action-adventure stealth game developed by Acquire for PlayStation. Players control two Azuma Ninja, Rikimaru and Ayame, in third-person view, completing assassination missions across 30 levels while avoiding detection. The core gameplay emphasizes stealth kills with precise sword strikes from behind or in shadows, using items like caltrops, shuriken, and grapple hooks, plus special moves such as double-step or wall-hiding. Story follows the ninjas' duty to eliminate evil forces led by the Demon King, with supporting characters including Princess Kiku. What makes it stand out is its innovative early-3D stealth mechanics, dynamic enemy AI, customizable levels via the Tiger's Roll editor, and realistic ninja combat that influenced the genre, blending tense exploration with brutal one-hit assassinations.
