Fight your way through 35 different types of enemies with bouncing bellies, blinking eyes, stretching tentacles and snapping jaws. From Prehistoric Raptors, to evolved Flesh Eaters, to your final battle with the Mother of all beasts— you'll want to defeat all of them! Enemies are intelligent! They're smart enough to attack in groups, to flee when they are outgunned, and to take cover during a firefight. Enemies flinch and spasm differently depending on which body part you hit.
