2. Beneath a Steek Sky Reference: In the London underground, a ghost appears at the right end of the screen but disappears if you try to talk or come close to her. Get the chocolate bar from the vending machine and try to give it to the ghost. She won't take it. Now, if you point your mouse to the left end of the screen, you can see that there is a new exit. Go there and a cutscene about 'Beneath A Steel Sky', one of the first Revolution Software games, will appear.
