About this game
Tenchu: Stealth Assassins (1998) arrived the same year as Metal Gear Solid and established stealth gameplay on PlayStation from a radically different perspective — third-person, open feudal Japan, with a KI meter that rewarded pure stealth over violent engagement. Developed by Acquire as their first project, with a score by Noriyuki Asakura blending Japanese, Chinese, Thai, and Turkish musical influences, it sold over one million units and launched a franchise that defined the ninja action genre for years.
Key Features
KI (killing intent) meter: a stealth rating that tracks whether enemies can sense the player. Performing stealth kills maintains a low KI and unlocks better item rewards at mission end. Two playable characters with different abilities: Rikimaru (heavy swordsman) and Ayame (fast dual-wielder). Open 3D mission stages set in feudal Japan with rooftops, gardens, and castle interiors. Grappling hook for rapid vertical traversal. Cinematic pre-rendered cut scenes advance the story.

The Story Behind
Tenchu was Acquire's first project as a developer — the company was founded specifically to make this game. Stealth gaming in 1998 was defined almost entirely by the upcoming Metal Gear Solid, which also released that year — but Tenchu offered a completely different approach: open 3D levels, real-time stealth mechanics, and a feudal Japanese setting. Publisher Sony Music Entertainment Japan took an unusual role in publishing a video game. Activision distributed the title in Western markets, where it sold well against its competition.
Tricks & Tales
Composer Noriyuki Asakura, who scored Tenchu, was already known for the Rurouni Kenshin anime soundtrack — bringing genuine Japanese musical expertise to the game. The KI meter was an innovation in stealth game design: instead of a purely binary 'seen/unseen' system, it gave a continuous readout of detection probability. A demo of Tenchu included with later PlayStation games helped introduce it to a wide audience before its Western release.
