Atlantis II (Known as Beyond Atlantis in North America) is a fantasy adventure computer game developed by Cryo Interactive and published by Dreamcatcher Interactive, and released in 1999. It's a sequel to Atlantis: The Lost Tales. However, unlike its precursor, not much of the game is based around Atlantis. It was followed by Atlantis III: The New World.
In this adventure game, take Ten, the Bearer of Light, through his journey to Shambhala to confront the Bearer of Dark so that balance can be returned to the Universe. To find Shambhala, he must gather the pieces that make up the "road to Shambhala" from different locations and time periods - China, Ireland and the Yucatán.
The game features a "point and click" interface, full 3D panning, puzzles of varied difficulty, conversations with other characters, and a fully-orchestrated musical score.
