Ni Bi Ru: Age of Secrets is a graphic adventure, full of mystery and conspiracy, that spans interests in modern-day archeology, World War II Germany, and ancient Maya civilization. Players take the role of a young linguistics student named Martin Holan, who has been invited by his uncle to investigate a recently unearthed tunnel, believed to be left behind by Hitler's Third Reich. Ni Bi Ru features more than three dozen key non-player characters, each with a different perspective and personality, and the game plays out through 80 detailed locations. The adventure begins as Martin arrives at the site and finds that the contact he was supposed to meet has been murdered. Martin's first task will be gaining access to the excavation site, but far deeper mysteries and greater challenges surely await at the end of the tunnel. ~ T.J. Deci, All Game Guide
