As you fight your way down through the alien hive of flesh, polyps and skulls, killing tumour-like acid turrets, mutated and brainwashed Human soldiers and alien eggs spawning newborn warriors ready to rampage right from the womb, you fall down a ledge. Standing up, you find yourself in front of a titanic humanoid statue of alien flesh and bone with dozens of dead alien eggs lying around. A spooky atmosphere permeates the surroundings as you notice the giant skull grinning maliciously.
