Zoran Lazarevic is the primary antagonist of Uncharted 2: Among Thieves. He is voiced by Graham McTavish. He is a homicidal terrorist and Serbian war criminal. The majority of the world believes him dead after a bombing, but he survives with half of his face scarred. Lazarevic pays Flynn to betray Drake, tricking him into giving Flynn information on the location of Marco Polo's lost fleet and causing Drake's arrest. In reality, Lazarevic wants to possess the mythical Cintamani Stone, which the fleet was supposedly transporting. He discovers that the fleet never had the stone, and dispatches a group of mercenaries to Nepal for clues to the location of the legendary city of Shambhala. He incites a civil war in the region to aid in his search and distract from any possible discovery. In Nepal, Lazarevic personally executes Fisher's cameraman Jeff, and follows Drake after he discovers the location of Shambhala's entrance. Lazarevic invades the small Tibetan village harboring Drake and Elena, seeking the key to reveal Shambhala. He kidnaps Schäfer and forces him to reveal the general area of the entrance. When Drake and Fisher follow, Lazarevic apprehends them and forces Drake to reveal the entrance to Shambhala. There, he drinks the sap of the Cintamani Stone, which is made of the sap of the Tree of Life. He battles Drake with his newfound powers, but is defeated by Drake and beaten by the guardians of Shambhala and assumingly killed when the temple fell apart. Lazarevic uses a sawed-off shotgun as his main weapon.
