Was Tenchu 2 a prequel to Tenchu: Stealth Assassins?
Is Suzaku and Onikage the same character ?
Finish the game with Tatsumaru to play an animated scene where Suzaku removes his blindfold to reveal that he is in fact Onikage from Tenchu 1. He then speaks dialogue relating to the coming of Lord Mei-oh, which sets the scene for Tenchu: Stealth Assassins.
How do I unlock Tatsumaru ?
To unlock Tatsumaru you must finish the game with both Rikimaru and Ayame. There is also a cheat on the cheats page.
Is there a debug mode for Tenchu 2 ?
Quite simply, no.
