Character: The Son
This is the final boss encounter of the game, featuring The Son in a drug-induced hallucination. The fight is broken into several distinct phases, each requiring a different approach. You'll be playing as The Son, and your abilities will change with each 'form' he takes.

- Phase 1: Tiger Form
The Son transforms into a tiger, similar to Tony's abilities. You can only use melee (claws) but have an instant-kill attack. The room is filled with enemies. Use your speed and instant-kill attacks to clear them quickly. This phase is a test of your melee combo skills. Prioritize enemies with firearms.
- Phase 2: Bear Form
The Son transforms into a bear, similar to Mark's abilities. You can dual-wield SMGs. The room will likely have more open spaces and numerous enemies. Use your dual SMGs to clear the room aggressively. Be mindful of ammo and reload behind cover. This phase is about overwhelming firepower.
- Phase 3: Swan Form
The Son transforms into a swan, similar to Alex & Ash. You'll have a chainsaw and a pistol. This phase often features a mix of close-quarters and ranged enemies. Use the chainsaw for immediate threats and the pistol for distant ones. Coordinate your attacks, remembering the strengths of both weapons. This phase requires a balanced approach.
- Phase 4: Final Confrontation
The final phase is often a chaotic mix of all previous forms or a unique, highly aggressive form. The environment might be collapsing or changing. The key here is to adapt quickly to the changing abilities and enemy types. There's no single 'trick'; it's a culmination of all your learned skills. Keep moving, prioritize threats, and use whatever abilities you have to survive.
