Onimusha 3: Demon Siege Cheats

You can get the Panda costume for Samanosuke (which is really weird in
my opinion and useless) get have an Onimusha Blade Warriors or Onimusha
Buraiden (sanme as Blade Warriors excecpt in Japanese). AND VIOLA.
Youhave the Panda Costume.

When you are fighting Nobunaga when he is in his demon form, press Square(2), Triangle. This is a great combo move, but do not overdo it with him. When you absorb the darkness from his sword and you get it, remember that some of his moves cannot be blocked (such as the charge and the fireball moves). You can only block one or two. For the charge move, press Triangle at the last moment when he is on fire and you should dodge it. For the fireball move, just have enough space to run around.

Finish the game one time using hard mode.
Now start a new game and during gameplay press L1, L2, R1, R2, Circle Square, Square, Triangle, Circle.

To get the ultimate mode, beat all the levels of the Oni Target Practice minigame.(beat the game in normal mode to get it) In ultimate mode you start with the Bishamon sword and Ultimate Whip, all your weapons will be at MAX level and have unlimited magic, and your characters will each have a bunch of ultra medicines and charms. NOTE: You have to turn it on in the special features thing.
