Microsoft announced today that Tenchu Z will be exclusively developed for the Xbox 360 by FromSoftware. Tenchu Z will continue the Tenchu franchise with more than 50 stealth Ninja missions set in ancient Japan. Players will be able to use an assortment of ninja weapons (including grappling hooks) on the way to defeating the big Boss. They will also be able to obtain new skills and weapons based on the use of sound, sight and smell. Leveling up is done more by using patience and strategy rather than charging ahead with guns blazing. No release date or rating are available at this time.
