Boss Rush Cheat Codes
You can put modifiers on your boss rush runs if you hold down one of the following buttons and then press start on a boss rush:
- i – Nightmare Mode Boss Difficulty
- N – Ultimate Zangetsu (normal boss difficulty)
- T – Infinite Weapon Points
- C – Subweapons and Hearts Regenerate After Each Battle
Multiple of these can be active at once, assuming you can manage to hold down all the buttons and still press start.
