The Omega Stone is the sequel to Riddle of the Sphinx, and equally epic in scope. But this time, you are on an adventure that takes you to the ends of the earth as you explore the Giza Plateau and Sphinx once again, plus Stonehenge, Easter Island, Santorini (looking for Atlantis), the Bermuda Triangle, and the Mayan monuments at Chichen Itza. Along the way, you will meet quirky and mysterious characters, and discover a treasure trove of secrets. What is the Omega Stone? And why is the cryptic warning about an impending revelation so dire?
