In Uncharted 2: Amongst Thieves fortune hunter Nathan Drake embarks on a journey that will push him to his physical, emotional and intellectual limits to discover the real truth behind the lost fleet of Marco Polo and the legendary Himalayan valley of Shambhala, more commonly known in the west as Shangri-La. In 1292 Marco Polo departed the court of Kublai Khan in China with 14 ships filled with over 600 passengers and crew. Eighteen months later only one ship remained and 18 passengers survived. Marco Polo never revealed what happened to these lost ships. Embarking on a quest to find the lost fleet, fortune hunter Nathan Drake soon realizes Marco Polo was hiding a much bigger secret - he had gone on a secret expedition to find the mythical kingdom of Shambhala and to recover the legendary Cintamani Stone, the "Wish-fulfilling jewel" of Buddhist mythology. With this new information Drake settles on a new course, following Marco Polo's trail through a diverse range of exotic environments. This quest also pits him against a new, more formidable adversary - a ruthless, rogue paramilitary leader with a private army and a relentless ambition to recover the stone for himself.
