After fighting through the headquarters, the climax moves to the rooftop. Here, you will face a series of challenging boss battles, often in quick succession. The game will strategically assign you a character for each fight, or give you a choice. Be prepared for multi-phase boss encounters, where enemies change their tactics or gain new abilities as their health depletes.

For each boss, refer to the 'Boss Guides' section for specific strategies. Remember to use your healing items wisely. The final boss of the game will be a true test of your mastery of all four characters' combat styles. Pay attention to their tells, block and dodge effectively, and unleash your most powerful Heat Actions when opportunities arise. Successfully defeating the final boss will trigger the game's ending cutscenes and conclude the main story.
