Lighthouse: The Dark Being is now available DRM-free, only on GOG.com.
A first-person adventure by masters of classic point & clicks, Sierra On-Line. What goes on inside that eerie lighthouse, occupied by the eccentric Dr. Krick and his little daughter? The mysterious message on your answering machine prompts you to enter, only to find its inhabitants gone. Violently transported to a parallel universe by a malevolent entity, their only hope now is that you’ll cross to the other side, overcome the devious puzzles, and bring them back safely.
