I also like the Xenos killing the Guardsmen, its a well done scene, with blood mingling with the rain to cover windshields. The scene makes me wonder if the Brothers Straus wanted to do Colonial Marines film with the Predators in the future, but what hindered them was The Predalien, they wanted to feature it and AVP1 set it up already, allowing them to piece together a easier script since its a sequel to the first film.
