IT HAS SURVIVED



At a research station in Antarctica, scientists discovered a strange and ancient organism.


They thought they could study it, classify it, control it. They couldn't.



IT HAS THRIVED



Six months ago, a secret paramilitary team called Unit 51 was sent to the station.


They thought the creature was dead, the nightmare was over. It wasn't.



IT HAS EVOLVED



In a Mexican temple, archaeologists uncover the remains of a half-human hybrid. They believe it is related to the creature in Antarctica, a dark thing of legend that is still alive—and still evolving. They believe it needs a new host to feed, to mutate, to multiply. They're right. And they're next. And the human race might just be headed for extinction . . .
