Ugh-Zan III is the final boss of Serious Sam: The First Encounter, a colossal, multi-limbed monstrosity that serves as Mental's ultimate champion. This fight takes place in a large, open arena with several pillars and structures. Ugh-Zan III has multiple attack phases and requires a combination of dodging and sustained firepower to defeat. Ensure you enter this fight with maximum health, armor, and full ammo for your Rocket Launcher, Lasergun, and especially the Cannon. If you have any Serious Damage or Invulnerability power-ups, save them for critical moments in this battle. The arena often contains additional health and ammo pickups, but they are usually in dangerous locations.
