For instance, if those albino body builders failed their mission to destroy earth all those years ago, why wasn't earth subsequently destroyed by another team? Why bother destroying earth with such a bizarre method that then leaves the planet full of mutants... why not nuke it etc? The xenomorph at the end seems to be the only link as a prequel to Alien. :/
Also, what were those albino body builders all running away from and killed by when piled up by the door? There's no clear cause of death, nor explanation for why they could've just been waiting there to die.... given the doors can still open very easily when the humans arrive.. o.0 And no reason why that last albino was in a hypersleep chamber in the first place... instead of doing his damned mission.
