You woke up on the ground after your helicopter crashed due to engine failure of some sorts, the darkness surrounding you with only your flashlight and the night sky guiding your way. The area you landed in seems to be a large facility or station type of structures mixed with a park sort of which were sealed off by the public with tall electric fence being 10 km away from where you are right now, surrounded by the dread of the trees. It was raining softly which caused the fire of the helicopter to die out along with moist and fog building up, you then got up and observed your surroundings.
After only some seconds you heard a roar in the distance, but one of a dinosaur, though luckily it didn't seem to be close where you were standing so you still had time to grab some supplies and explore this seemingly endless facility park.
