Hidden Boss and ending:
Complete story mode without getting hit to fight each character's secret boss. Note: This includes not using any continues and following the code of Bushido.

Fight as Katze:
Beat all 100 opponents in slash mode without getting killed.

Fight as Sanzaka:
Unlock Katze, then switch to the hard difficulty setting and get through slash and story mode with him. You will now have Sanzaka (The idiot on the beach with a Mod. Naginata). Note: When selecting Katze, you will see nothing. When you have chosen the weapon, you will see the weapon bow to Ling/the opponent.

Hint: Explore other areas:
In some areas of the game you can enter different locations by having your fighter and your opponent run to a wall. Wait a few minutes while running and you may enter in a different area, This trick does not work in some areas, such as like bamboo thicket.

Glitch: Chain-saw effect:
You must have the broadsword or Naginata for this trick. After you kill an opponent, make sure your feet are directly next to their shoulders and their head is under you. Wait for the winning pose to appear. If done correctly the broadsword will hit their head and blood will start to spray everywhere. Note: This does not work in slash mode.
