Tenchu: Stealth Assassins

Description

After firing your grappling hook to the rooftop of a small house, you pull yourself up and notice a guard pacing back and forth on the ground. He doesn't see you as you begin to crawl and sneak around on the roof. If he detects your presence, you will be in a world of hurt; you will blow your mission and risk death. Patiently, you wait for the right time to jump down -- and end his life while his back is turned.
