Enable the impulse 101 code. Once you are in the main room, go to the bathrooms and open your locker. Take out a powerful weapon or a crowbar and crouch down and start beating (or shooting) the box. After beating the box with a crowbar over 50 times, or shooting it with a laser or some other powerful weapon, it will break open. There will be a little live alien in the box. You cannot do anything to it except look at it.
