After taking significant damage, Ugh-Zan III will often retreat to a higher position or become more aggressive, introducing new attacks and summoning minions. It might start firing faster projectiles or even a continuous laser beam. During this phase, it will also summon waves of smaller enemies, such as Headless Kamikazes, Kleer Skeletons, and Harpies, to distract you. Prioritize taking out the minions with your Minigun or Shotgun to prevent them from overwhelming you. Continue to target Ugh-Zan III's remaining weak points with your Rocket Launcher and Lasergun. If you have a Serious Damage power-up, this is a good time to use it to quickly burst down a weak point. Maintain constant movement to avoid both the boss's attacks and the incoming minions. Ammo pickups might appear in the arena during this phase, but be careful when collecting them.
