A jurassic horror

I started with an idea of an 2d game like the jurassic park games for nintendo, then i joined a game jam and made a 3D game, and my idea changed, now i'll make a horror 3d game with dinosaurs! well, i know there is already dino crisis series, but i want to do something on my own, i want to bring the idea alive, so i will accept suggestions and tips! The main story that i thought was: A random soldier that the name i still don't figured out, was called in the radio while he was resting in the headquarters, the message said: "We need back up, something weird is going on here, we're sending the coordinates, over!" then with a few fellas he enters in the car and go to the coordinates, as soon as he get in the location, a big explosion happens, then he pass out, when he wakes up he is in the middle of the jungle, without his weapons, without nothing but a knife and his radio, that is broken, then he start his little adventure! i still working on the game idea while i download and make the assets, so anyone that have anything to add to the story, i'll accept!
