This PSP entry in the series has you as ninjitsu masters Ayane and Rikumaru in an all-new storyline that takes place immediately following the events of Tenchu: Fatal Shadows. Each character is tied to a different story, and each story offers different levels to play through. In addition to the scenario mode, there is also a 'free mission' mode that's comprised of 50 independent missions to enjoy after you have completed the single-player campaign.
From Software resurrects the mission creation mode from Tenchu II for this handheld edition, allowing you to create your own maps, complete with enemies. These can be saved to Memory Stick for exchange with friends. Players can also engage in cooperative and competitive multiplayer play with multiple selectable characters, both through wireless LAN and USB cable.
