Boss Rush mode pits you against all the bosses from the main game, one after another, with limited health and Overdrive. This mode is a true test of your boss-fighting prowess and endurance. Each boss retains its original attack patterns and weaknesses, so refer to the 'Boss Guides' section for detailed strategies. The key to success in Boss Rush is:

- Resource Management: Carefully manage your Overdrive stock. Only use it when absolutely necessary to avoid critical damage or to quickly clear a phase.
- Pattern Recognition: Memorize each boss's attack patterns to anticipate and evade incoming fire.
- Efficient Damage: Focus your fire on weak points and maximize your lock-ons to deal damage as quickly as possible.
- Health Preservation: Avoid taking unnecessary hits. Every point of health is precious.
Completing Boss Rush mode often unlocks special achievements or visual filters.
