Echo: Secrets of the Lost Cavern (2005)

Secret of the Lost Cavern is another edutainment Myst-clone adventure in the tradition of old Cryo titles. This game attempts to take us to the Prehistoric Age. The storyline revolves around the famed Lascaux Caverns of France, where our direct ancestors, the Cro Magnon humans, have left a significant legacy of wall paintings. The hero, Arok, is a young hunter/gatherer who is more interested in painting, however. He soon discovers that he can influence the world around him by painting on the cavern walls, as he searches for a mysterious mentor.
