The Sanitarium: The Foyer expansion includes a revised rulebook for Sanitarium--which completely replaces the original rulebook, a Foyer starting location, four double-sided Character cards, and revised scenarios (which also completely replace the originals). The Solo Scenario was unintentionally omitted from the revised scenario cards, but a printable PDF may be found at the Asmadi website at http://asmadigames.com/files/sanitarium_solo.pdf
