An ancient map leads you directly to the legendary tomb of Osiris. After weeks of digging you finally unearth the enormus entrance gate to the pyramid. As you step inside the huge cylindrical entrance room, you suddenly hear a disturbing scraping noise. From a hole in the ceiling, sand behins to flow into the room at an alarming rate. You estimate you'll only have one hour to find the treasures inside the tomb of Osiris and get out before this ‘giant hourglass’ will forever block your way to freedom. —description from the publisher
