Oh and the Bros Strause need to go, sorry. Wasn't impressed at all with their direction. I'd bring in Neil Marshall(The Descent, Dog Soldiers) to direct. The movie takes place years after the events of Aliens(before Alien 3 though) The company has set up a huge top secret military complex on LV-426 and has retrieved eggs from the derelict to start mass producing Alien warriors as military weapons. We find out that the Space Jockey is actually viewed as a "God" to the Predator species and another beacon is activated in the derelict accidentally when a company scientist is collecting eggs. This beacon goes out to the Predator homeworld which brings the Predators to the planet. Meanwhile, a squad of Colonial Marines(who are helping guard the installation) revolt against the company's plan to use the Aliens as weapons and decide to try to sabotage the complex by blowing it up. Needless to say, the Aliens get out in the complex and the Predators show up and the marines end up fighting the company, predators and aliens!
