The final boss, The Patriarch, is a multi-phase fight that will test all your skills. He combines elements of both brute force and tactical gadgetry. In his first phase, he's aggressive and uses powerful Yakuza-like attacks. In later phases, he might incorporate his own unique gadgets or summon allies. You'll need to seamlessly switch between Yakuza and Agent styles, manage your Heat Gauge, and utilize all your unlocked abilities. Stock up on healing items before this fight.

Strategy:
- Phase 1: Focus on Yakuza Style, dodge his heavy attacks, and counter.
- Phase 2 (if applicable): Adapt to new gadgets or summoned enemies. Use Agent Style for crowd control or ranged attacks.
- Heat Actions: Save your most powerful Heat Actions for when he's vulnerable or when you need to burst damage.
- Resource Management: Use healing items strategically. Don't let your health drop too low.
