Ugh-Zan III

Ugh-Zan III is the final boss in Serious Sam: The First Encounter and Serious Sam HD: The First Encounter.

Ugh-Zan III is one of Mental's generals, ranking as Great Admiral in Mental's Horde. Ugh-Zan III is the third incarnation of the vicious Ugh-Zan, the last of the warlock giants. He was sent by Mental to supervise the assault on Earth. He is one of the most dangerous creatures in the universe.

Ugh-Zan III is a very large creature but very slow. He moves at the same speed as the player does (10 speed in the database, just like Sam), has 4 arms, which come with 4 weapons, can breathe fireballs or stomp the player and can regenerate his health when it's low. He regenerates his life when he has about 5% health left (when the life bar turns red and is nearly empty). He is stunned, disabled and immobilized when hit by the laser beam, so in that case he can't regenerate.

The boss fight comes in 3 stages: running away from him, waiting for the Pyramid Door to open, and the last fight. In the first stage, you just run away from him, as he chases you through the Arena to the Great Pyramid. While you're doing this, Biomechanoid Minors, Biomechanoid Majors, Kleer Skeletons, and Sirian Werebulls are rushing you.

In the second stage, you will have to survive against him until the Pyramid Door opens, which will take some time. Ugh-Zan will take out his Lava Bomb Launcher and Laser Gun when he reaches the Pyramid's ramp.

In the third stage, he will jump inside the Pyramid Arena, pull out all his 4 weapons (Lava Bomb Launcher, Rocket Launcher, Laser Gun and Electric Gun). To kill him, you will have to activate all four rings around the arena, get him in the middle and zap him with the spaceship's laser beam. In SSHD, a laser beam is automatically fired once when you enter the pyramid.
