Tenchu: Shinobi Taizen is situated shortly after Tenchu 3 and revolves around the series' hero and heroine, Rikimaru and Ayame. Both characters will have their own missions in scenario mode, and there will be multiplayer head-to-head through PSP's Wi-Fi or USB connections. Tenchu: Shinobi Taizen will also include an editor to make your own missions, buildings and place enemies, all saveable on a Memory Stick Duo.
