Bakong (2009)

In Bakong you experience a hunt for the most beautiful emeralds in the Cambodian primeval forest. You start from your base camp to reach a temple where you collect precious jewelry.
Players carry a rucksack with items for their survival and later on use it to return the jewelry. But the pathway through the jungle is insidious because routes are changing all the time and traps are laid out for you. The goal is to collect as many emeralds as possible and return them to your base camp.
