Adrenaline is running high as you snake your way through the top-secret research facility. At the end of a long corridor, you duck into a lab filled with black-topped tables. Something isn’t right, but you aren’t sure what it is. You take a moment to look around and notice that half the room is missing air hoods. You look up, hit a button on your game controller, and the ceiling peels away as if it were the skin of an onion. Someone forgot to add several key parts of the mechanical system into the model.
