Be sure to grab the health and armor pickups in this building. This building has a jetpack (in the Fusion version, the jetpack is located in the middle of the arena), which is required to kill Ugh-Zan IV (this means that it is impossible to beat the boss if the player has power-ups turned off to increase their score, because that stops the jetpack from spawning). As soon as the battle starts, go left into the building nearest the large structure in the center of the arena.

He has very high health regeneration that increases the lower he is on health, and while regenerating, he is immune to the player's weapons. He's generally not considered as difficult as Ugh-Zan III. He will stomp on the player at every opportunity at close range. His primary attacks are firing wide, fast-moving projectiles, that while easily dodged, do a considerable amount of damage. He can also spin quickly on his cybernetic base, allowing him to deal with threats who may be trying to attack the vulnerable weak spot on his back. Like Ugh-Zan III, Ugh-Zan IV can move quite fast, despite his size.

Periodically, he will wrestle with the Sandwhale. He is a very large creature, with four arms (two natural arms and two augmented ones) and four large legs, which serve as a bio-mechanical quadruped which act as a base replacing the legs.ĭuring the fight, he will be constantly surrounded by Mental's forces ( Khnums, Major Bio-mechanoids, Minor Bio-mechanoids and Technopolyps) and will spawn in reinforcements until either he or Sam is dead. Ugh-Zan IV is alleged to be the biological father of Ugh-Zan III, a paradox attributed to an accident with an experimental time-machine.
