I actually saw a raptor stick his head through a wall but not in a cool way. Also, a few trees seem to hover in mid air. They only give you one inventory slot, so despite the fact that there are many real-world guns to choose from, you are limited to carrying one at a time. You can stow one and carry another, but you have to keep that second one in your hand, which is difficult to manage. But if you are sick to death of plain old action, have the computing horsepower to wrangle this beast, hunger for a thoughtful, innovative, realistic adventure, and above all, have an abiding love for dinosaurs, Site B is the perfect vacation spot for you.
Raptors like to hide.
Best to circle an area with your gun drawn. If you hear a growl, freeze, draw your weapon, and be ready. Also, if a raptor is approaching, try to keep trees and objects between the two of you. If you must run for it, weave and jump. Always switch guns when you find a new one.
