In The First Berserker: Khazan, players will find themselves up against a wide array of dangerous and unique foes. Every major mission concludes with a challenging boss fight, while additional bonus missions offer even more powerful adversaries for those who seek them out.

No two fights are the same, and players must adapt to each boss’s abilities to succeed. This guide provides a complete list of every main and optional boss in the game, along with recommendations and context for each encounter.
