The environment and attention to detail on the dinosaurs is pretty impressive, with Crytek Producer Fatih Ă–zbayram taking to Twitter to describe the demo:
"Our demo has a variety of interactions. One of them is the interaction with a Hollywood feel T-Rex which mimics your head movements. The narrative [of] our demo is you being a baby dinosaur sitting in the middle of a nest of other dinosaur babies about to hatch. We've chosen dinosaurs as we wanted to nod to the origins of Crytek".
