Alexa and Sebastian decide that the Predators must be allowed to succeed in their hunt so that the Aliens do not reach the surface. Unfortunately, Sebastian is captured by an Alien, leaving only Alexa and the Predator to fight against the Aliens. The two form an alliance and use a self-destruct device to destroy the pyramid and the remaining Aliens. Alexa and Scar reach the surface, where they battle the Alien Queen. They defeat the Queen by attaching its chain to a water tower and pushing her over a cliff, dragging the Queen to the ocean floor. It is unknown whether this killed the Queen, as Xenomorph creatures have been seen to survive submerged in water for extended periods of time. Scar, however, is impaled through the torso by the creature's tail and succumbs to his wounds.
