This unusual graphic adventure is set in a prehistoric time and casts players as a hunter-gatherer hero at the dawn of human civilization. While the point-and-click interface and inventory puzzles should be familiar to fans of the genre, players will be transported to a world not seen by human eyes for 15 thousand years. The game features a built-in encyclopedia of information on the Paleolithic era, to help modern players find their way around. Echo: Secrets of the Lost Cavern was developed by Kheops Studio, known for its earlier adventure games Egyptian Prophecy and Return to Mysterious Island.
