Onimusha 3: Demon Siege Cheats


Adventures Of Heihachi (Heihachi Buraiden) Mode
Successfully complete the game. Heihachi (Honda) is now selectable.
Ako's Black Haori
Successfully complete Issen/Oni training to unlock Ako's Black Haori.
Alternate Ending Sequence
Increase all seven Haori of Ako to the maximum to view the alternate ending sequence. This requires all Kodama to be found.
    Bravery: Successfully complete the game without saving.
    Critical: Kill over 40% of your enemies with critical hits.
    Defense: Take less than 5,120 damage.
    Explorer: Find all 23 Tengu chests.
    Offense: Kill over 3,000 enemies.
    Speed: Have a completion time of less than 5:00:00.
Bishamon Sword
Successfully complete the game with the "Onimusha" rank. Alternately, get the Bishamon sword in the Phantom Realm in Honnouji when Sam goes to the past.
Bypass Dark Realms
Any of the three Dark Realms can be easily bypassed. This requires some skill, Ako's Purple Vest, all weapons for the character, and all weapons been completely enhanced. Whether or not the gauntlet is completely enhanced is irrelevant. Before entering the Dark Realm, equip either Chigo (for Samanosuke) or Hyosai (for Jacques). The enemies that attack will appear in multiple waves. Just wait for all enemies to appear, then execute one magic attack. Absorb all the souls that appear. Ako's Purple Vest should allow you to do this as many times as necessary. However, if you are fighting large demons, you may need to get up close with either the Tenso (for Samanosuke) or the Enja (for Jacques).
Note: A crucial part of this strategy is absorbing the souls. If you feel that you need Ako's Blue Vest as well, make sure to switch back and forth as appropriate. Also, it is much easier to go straight for the bottom part of the Dark Realm that you are in, as the tougher enemies are down there first. By doing this, you can use your magic efficiently on the tougher enemies and not have to worry about the weaker ones.
Critical (Issen) Mode
Successfully complete the game on the hard difficulty setting to unlock Critical (Issen) mode. In this mode, only critical hits can kill opponents.
Defeating Guard Dog

Note: This was done under the normal difficulty setting. First, stock up on magic for all your weapons. Then, stock up on all the Purple Souls. At the beginning, jump behind him after he attacks. Then, just waste the magic on him. Use every weapons magic until you do not have any more. After that, use regular attacks. Watch out for the ice attack. Most of the time the thunder magic from him is off target. After a few regular attacks, transform into the Onimusha and attack him hard. However, do not use the mega attack yet. After a few attacks, just before your magic runs out use the mega magic attack on him. If he is not defeated, then just attack him a few more times.
Defeating Nobunaga
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.
Deflecting Critical Hits
Repeatedly tap Guard until someone hits you. And as soon as you see the flash, tap Square . Keep tapping Square to go from enemy to enemy, racking up multiple critical hits.
Easy Difficulty
Intentionally lose the game two times on the normal difficulty setting to unlock the easy difficulty setting.
Genma Puzzle Mini-game
Solve all the puzzles in the game to unlock the Genma Puzzle mini-game.
Hard Difficulty
Successfully complete the game on the normal difficulty setting to unlock the hard difficulty setting.
Infinite Genma Souls
After going through the first set of double doors where the Oni Army is fighting the Genma, before using the Firefly to go up the short cliff, have the Genma and and Oni Army men on the wall of the short cliff and you as close as possible to the doors on the other side of the field. The supply of Genma infantry are infinite and Oni Army can take care of them by themselves. While they are fighting and nowhere near you, tape down Circle and allow the game to run. The souls will come to you, and you can get as many as desired without interruptions from the Genma. For a slightly faster collection, have Ako's Blue Vest equipped.
Note: The process of getting a lot of bars filled of souls will take a long time. Also, when the soul count reaches 9,999, release Circle. This gives you an additional bar (or perhaps more) filled automatically. Then, tape Circle again. Given enough time you can have 99 bars worth of souls.

Note: This trick only works for Samanosuke. Once you obtain the Ten-Point Slash Training Scroll, play under the beginner difficulty setting multiple times. Each time you finish, you should come away with one bar, or close to it. Do this until you have the desired amount of souls, or until you max all your equipment.

Oni Musou
Have Jacque go through the Phantom Realm in Honnouji.

Panda Costume
Successfully complete secret training mode to unlock the panda costume. Alternately, play the game with a memory card with a saved game from Onimusha: Blade Warriors.
Regain Health
Equip Ako's White Haori, then stand still. Additionally, when Ako's wearing the White Haori, rotate the Right Analog-stick. Ako will move faster to regain health quicker, depending how fast you can rotate.
Note: Do not not use it while you have five Oni Orbs.
Secret Training Mode Mini-game
Successfully complete normal training mode, then complete the game to unlock the secret training mode mini-game.
Skip FMV Sequences
Successfully complete the game. When playing the game again, press Start to advance past any intermission sequence.
Ultimate Mode
Successfully complete the Oni shooting mini-game to unlock Ultimate mode. The game will start with Sam having the Bishamon sword; Jacque having his best Oni Musou; infinite arrows, bullets, infinite Oni power, thirty Medicines, and ten Talismans.
Use Less Magic During Magic Attacks
This trick requires the gauntlet for Sam/Jacques to be at least level 2. Charge up the gauntlet (press R1 firmly) to at least two and unleash a magic attack. With the purple vest on Ako you can do about five magic attacks in a row instead of four.
