WHat I think happens is the Predalien grows to adulthood and causes lots of mayhem on the Warship (Predator) The thing crashes back to Earth. There is also a Queen and her eggsack onboard that escapes when the ship lands near a small Colorado town. The Queen lays face huggers in the sewer which reach people and the Predalien is arounf too. Another clan sense this a send the fittest warrior (Wolf) to see what happened and by the time he gets there aliens are there, have nest in sewers and he has to exterminated them. Also the Howards (Ricky Dallas), O'briens(Tim Kelly Molly) Post (Nathan Dale) , and other families/people are caught in the middle. they basically need to survive this Predators "EXTERMINATION" of the aliens. The humans try to contact military, which doesn't come till end. More violence, no human survivors except maybe one. Also some absoulutley huge Predator ship that hold thousands of clan warships. Kinda like Trade Federation ships in Star Wars 1. Not a Star Wars fan but something that can hold many Pred ships and have an ultimate weapon like Dread Star or Death Star w/e it is. The Wolf kills Queen and Prealien and a couple of military tanks (when military arrives) It shows another Pred ship (small one, not huge one that I though would be cool) is shown through space heading towards Earth. Back in town, Only a few people made it to saftey after Wolf is overrun by aliens.
