An alien space craft lands in the center of New York City, and from within comes a Xenomorh Queen and a single xenomorph warrior brood type who escape down a sewer tunnel and after the next few weeks many complaints of missing persons are called in and more happen each day. After a few months 99% of the city and surrounding tunnels have been visably infected. And will continue to infect cities every week they are left unchecked... Will the human species survive?
Battle - Xenomorphs vs. Todays trained US. Soldiers.
Troops have all nessessary equipment
Xenomorph's will infect anything that breathes that are large enough to accomidate the infection process (humans, cats, dogs, zoo animals, and any other animals im forgetting)
US. Troops cannot drop nukes for the fear of fall out.
Xenomorphs are restricted to one queen per city that has been taken over since arrival.
Does Humanity survive the perfect threat? Or does humanity die out in a blaze of glory never to be heard from again?
