That reminds me. The biggest revelation for me in the movie was that there was a ground war in Africa fought with the aliens for TEN YEARS. That was really interesting. I love the fact that there were survivors stuck on the planet holding out like that. And yet, at the end of THIS movie, the big massive invincible mothership immediately leaves the planet the second the Queen dies even though it was seconds away from cracking open the planetary core :-p I know they already explained that would happen but jeeeeeez. Also, they said in this movie, gee there must have been a Queen on the first invasion we killed.... but then why did the aliens in Africa keep fighting for ten years?
