Advance in game:
Go to the skull load-in screen. Type the following case-sensitive text, with spaces as noted: “Roberto Dan R Zaphod B [Space]”
After you type “Roberto”, Stauf will say, ” Duh…. that’s not it Karl!”. Ignore him, he is trying to trick you. After the “B”, type [Space], then any of the following letters to get to that point in the game:
??? a: End of disc one.
??? s: End of disc two.
??? d: End of disc three.
??? f: End of disc four.
??? e: The “Olive In Stein” riddle, good for using the Kellyn code.
??? g: The very end, at the “Let’s Make A Real Deal” intermission sequence.
Hidden video:
To see a hidden video, go to the television In Dutton’s room at a point where you can see the close-up view. Type “Kellyn”.
Mocking cheaters:
In The 7th Guest, typing “Zaphod Beeblebrox” gave you open house access. Doing this in The 11th Hour will only cause Stuaf to mock you.
