Dino Crisis/Fridge

Fridge Brilliance

 * While we do see several corpses throughout the laboratories, the complex is mostly deserted. If most of the staff were evacuated during the experiment, why didn't they make themselves known after things went wrong? It could be that the same circumstances that brought the dinosaurs into the future sent those people into the past where they now have to fight for survival in a Fate Worse Than Death.
 * The dinosaurs ate them.
 * Why there are so many carnivores. The Third Energy's exchange targeted the very Late Cretaceous, after the meteor impact had kicked up the dust cloud and started a nuclear winter. Plants died first, then plant-eaters, with scavenging carnivores briefly thriving before they eventually ran out of prey. It was just before this final extinction point that some of them were transported into the modern century. Also, the Therizinos are a previously undiscovered species, not genuine Therizinosaurs. - Blue Chameleon
 * After watching a Lets Play/Walkthrough on YouTube, and replaying the game. I asked my brother why would the T-rex smash through the window to eat two people? And it hit me just as he said it. The T-Rex is a fish out of water and hungry because of it. This also explains why it acts as a Super Persistent Predator throughout the game. It is in a time completely different to its own, the raptors and Therazinos which would be food sources are hiding inside and there are no herbivores for it to hunt. It smashes through the window because it is a brightly light box on what is otherwise and grey lump of stone and it sees movement in there. So it goes for it. This also explains why it eats Cooper (The guy with the radio) in the opening, it sees a beam of light and hears movement as it investigates so it starts running. Of course humans only provide so much. And with Regina it because a Road Runner vs. Coyote situation in wanting THAT one human. It attacks you the second time because it hears the antenna being activated. It attacks the heliport because it sees the lights and hears the sounds. Going after the big helicopter first because it would supplement him, but since it didn’t taste good it throws it to the ground and goes after the next food source, Regina. Later it follows the research workers. But it can’t eat them because the elevator is too small for it too move and ends up stepping on them. And once it gets out into the underground it sees you and knocks itself out due to space. In all three endings it tears down the facility tracking you as you are the last thing it saw before passing out. Plus there's that pride thing. Your smell wakes it up in Gail’s ending and it follows you to the hoverport in Rick’s ending. Gail’s trail of blood also makes it go to the hoverport first in the final ending. – Doc Yoshi, Wishing he hadn’t written this so late.
