SEGA also announced that Mystery Dungeon: Shiren the Wanderer, a Nintendo DS RPG developed by Chunsoft, has shipped to retail across North America. On a quest to the mystical Lair of the Golden Condor, Shiren the Wanderer and his ally, Koppa, venture through treacherous lands in an attempt to solve the mystery surrounding this legendary realm. Many other warriors have set out on this quest but none have survived the long, perilous journey through deep caverns, vast forests, and dangerous mountain passes.
