Secret attacks:
To perform a secret attack with the various characters, spin the Left Analog-stick and tap Square. Note: This may require a few attempts.

When using Tesshu, press X Circle. You will see red smoke around his arms. When you now punch somebody, they will catch on fire. This will only work for a short time, but you repeat it again. Note: This works for only Tesshu, unless you go to the versus mode and use different people, except for Rikimaru and Ayame.

Easy stealth kills:
This trick works better on high roof levels such as Rikimaru"s first mission. If you have trouble anticipating when to perform a stealth kill, use a Poison Rice. Throw it in front of the guard and slice him before he eats it. Then, retrieve your rice and repeat the attack. You must be on a roof or cliff to do this best.

Run or walk up against an enemy"s side or back and press Square (default) to stealth kill him. You can also stealth kill him in front, but you have to do this very quickly, before he notices you. Note: All stealth kills must be executed before the enemy notices you. Also, you can see different animations for each character depending on which side of the stealth kill is in view. Each character has a different stealth kill.

Easy kills:
Once you got the last special attack (Wrath Of Heaven), use it to take out Bosses. Throw a smoke bomb in front of them, because it takes time to charge. Also make sure you have plenty of health potions. Rikimaru"s move is the longest, while Ayame"s is fast and deadly.
