There seems to be a lot more lighting in some of these shots. I can only imagine the contrast from these areas and the areas shrouded in darkness makes them even more powerful. One idea I think will work great in this game is the idea of the machine. It moves constantly, which means any shadow you see move will make you flinch, thinking it's a creature. Then, when you simply assume it's a piece of machine's shadow later... it isn't.
