Okie, time to add my two cents in...
A large human military research facility has been constructed on one of the newer planteray claims of mankind for weapons and armament investigation. It is privately owned and very few outsiders know of it for there are rumors that a most unlikely - and nearly illegal -weapon is being "breeded" there.
The research: A Xenomorph Queen specialy bred to become compliant to human demands by means of having her cerebral functions hooked up to an exclusive CPU.
The weapon: Her children.
So far the experiments have been a success and the research facility is more than eager to put their weapons up for sale (literally) to the rest of humanity...
Except that the Yautja are less than happy to see one of their Hunting grounds turned into a human settlement. They percieve this as a direct challenge to their authority.
When the Hunters attack, the humans retaliate; and in the chaotic mess the CPU is destroyed, freeing the Queen. With no binds to restrain the Xenomorphs they are free to bite (or dismember) the hand that feeds them.
Phew! Just pulled that out of my rear end right now.
