In its final phase, Ugh-Zan III will become enraged, often glowing brighter and attacking with increased frequency and intensity. Its remaining weak points will be exposed, and this is your chance to unleash your most powerful weapon: the Cannon. The Cannon deals massive damage and can often destroy a weak point in one or two direct hits. If you have an Invulnerability power-up, now is the time to use it to stand your ground and deliver uninterrupted Cannon shots. Continue to dodge its attacks, which may include a devastating ground pound or a barrage of projectiles. Keep firing Cannonballs into its exposed weak points until they are all destroyed. Once the final weak point is obliterated, Ugh-Zan III will explode in a spectacular fashion, marking your victory and the end of Serious Sam: The First Encounter. Congratulations, Earth Defender!
