Only a true Xenomorph has the "Xeno Factor." But what is "The Xeno Factor"? The "Xeno Factor" is a Xenomorph's resillience, skillset and resourcefulness combined with their physical and mental abilities. And this story illustrates what a Xenomorph goes through, how they cope and what sets them aside from us. Supreme intelligence, agility, power, strength, overall superiosity.

Eighty years after Weyland-Yutani Corps discovered the aliens, and after multiple successful "bug hunts", another Xenomorph XX121 breach is detected on the a research facility on LV-687. Routine precautions are taken: send in marines to rescue the survivors and then bomb the site from orbit. However, when the marines discover that these aliens are something new, something different, and something much more deadly, this routine mission becomes absolute terror as they get locked inside the facility with limited ammunition and deal, mutant Xenomorphs.
