STORYTELLING DETAILS
Symbolism
This level stands out from other Uncharted levels
because it’s full of symbolism, and it deals with
human ambitions and love for danger. In ancient
mythology and religions, the cavern symbolises not
only the primitive nature, but also the fear of the
unknown, mystery, darkness and rebirth.
Narrative Outline
According to historical source, there’s an ancient treasure in Vietnam. In 1950 an expedition of 5
men was sent but never came back.
Nate is looking for clues to recover the treasure, but he finds himself
trapped in the Hang Son Doong cave. He can do nothing but to find a
way out. In doing this, he bumps into enemies on the trail of the
same treasure.
During the exploration, the player finds also the diary of an explorer,
which reveals more about the caves, the treasure and strange
happenings. The survived explorer, supposedly under the influence
of underground extreme conditions, reports a chase with an
unidentified creature. On the last page of the diary, the explorer reveals that inside the cave
everybody get to know their dark side.
The final revelation
Whoever enters the Hang Son Doong caves is going to face
the darkest side of human ambition
Don’t take it too seriously: the cave is inhabited by monkeys intrigued by the human presence.
Nathan spots some of them during his final escape.
