Onimusha 2: Samurai's Destiny Cheats (PS2)

A game with a samurai as main character can't fail to deliver a great gaming experience and Onimusha: Warlords proved that. Hacking and slashing in the medieval Japan, our hero, Jubei Yagyu must defeat the evil lord Nobunaga that has come to life once more. Although the gameplay of Onimusha 2 is mostly constituted by a session of square button mashing, the fast-paced action and the best FMVs around will keep you glued to the TV screen for weeks. Capcom has a tradition for implementing tons of bonuses and unlockables in their games and the Resident Evil series is the best example for that. Here's a list of cheats and unlockables:

Easy mode
Start a game and die three times. A message will appear to indicate that a new easy difficulty setting is available. Note: You cannot achieve an Onimusha rank when playing in easy mode.

Hard mode
Successfully complete the game under the normal difficulty setting.

Critical mode
Successfully complete the game under the hard difficulty setting.

Ending bonuses
Successfully complete the game to unlock the Scenario Route option, Man In Black mode, and Team Onimusha mode; as well as a FMV preview of Onimusha 3.

Team Onimusha one hit kills
Successfully complete the game in Team Onimusha mode to unlock an option to replay Team Onimusha with one hit kills.

Ultimate mode
Successfully complete the game under the hard difficulty setting. Enter the „Special Features" menu and enable the „Ultimate Mode" option to begin a new game with the Rekka-Ken Sword, 20,000 in money, 30 Perfect Medicines, 10 Talismans, all level 3 armors, unlimited ammunition, unlimited magic, and skill always full. Your NPCs will also have
unlimited sub-weapons.

Issen mode
Successfully complete the Oni Organization mini-game. You must hit with a One Flash attack in order to do damage to opponents.

Mind Twister mode
Successfully complete the game with all Paintings.

Jubei's alternate costume
Collect the Fashionable Goods item and successfully complete the game with an „S" rank. Enter the „Special Features" menu and enable the „Extra Jubei" option to dress her in leather and sunglasses (press L2 to toggle). In the Japanese version, successfully complete the game with the Onimusha rank.

Oyu's alternate costume
Get a 100% scenario completion by playing the game multiple times to make good alliances with all NPCs. After all scenarios are unlocked in the „Scenario Route" viewer, enter the „Special Features" menu and enable the „Extra Oyu" option to dress him in a 1970's style costume.

Issen kill for all onscreen enemies
Get the book of Tech 2 so you can charge up any of your weapons three times. Then, perform the Issen kill, but continue holding Square. Jubei will do the Issen kill for all enemies on the screen. Do this to a lesser enemy such as a Crocodile Man or Rolling Orc to get the much larger one.

Instant kill
To instantly kill any normal enemy, walk near them and wait until they try to strike you. Just before it is about to hit you, tap Attack and a yellow streak will instantly kill the enemy. Note: This attack does not work on Bosses.

Easy Issen attacks
Move to your left or right for a thrust attack and press Square; move one step back for a slash attack and press Square; or use a timing attack on a rolling enemy.

Easy gold and souls
Go to the road to the gold mine. Some of Nobunaga's guards will be there. Kill them all, and they will drop some gold and some souls. Keep exiting the path and go back into it repeatedly.

Watching an Onimusha cutscene even beats watching the best anime around. Check this video out, but be aware that it's the ending FMV and it's a massive spoiler:
