Great adventure continues:
Examining the cave
Move forward and head straight until you reach a new place where you can use your grapple hook. This time, when you attach it, you must slide down on a rope (hold L1 button) because you must reach a huge lower chamber with new monuments of Parashurama and Ganesha.
When you land you must search for one more hook and just like before you must use it to slide down to a lower part of the cave. There, you can unlock a place to take a photo (3/4) and photograph the two previously mentioned monuments. Besides that you can also examine a corner, marked in the picture, where you can find a small stone elephant statue. Next to it there is a new treasure (3/6 - Bidri Hookah Bowl).
Finding an exit from the cave isn't easy. This exit is a small hole in a wall marked in the picture above and located right from an illuminated tree. Go through a tunnel and reach a bigger chamber. You must examine it carefully because there is a treasure (4/6 - Gold Cased Ivory Dentures)next to skeletons.
Approach the door with a similar mechanism found in Ganesha fort from the fourth chapter. Luckily, you don't have to do anything because the passage will be unlocked immediately. When you enter a new room you can have another optional conversation (4/5).
Find interactive edges on one of the walls, they will help you to leave the chamber in which you are currently in. When you reach a bigger location, where a small battle took place, you can check the area on the left. When you get there you can find a new treasure (5/6 - Palm Leaf Manuscript) (the picture above).
Use the stairs to go up and find a small hole in a wall, the heroines can squeeze through it. Finish your journey to the bigger chamber. Inside of it you can find a rather complicated puzzle that involves playing with shadows.
The solution for the shadows puzzle
Start by interacting with the rotating mechanism, this will allow you to activate the puzzle. You must move objects on the board in a such way that their shadows would overlap with the two pictures on the walls. Each one of the twelve mechanisms is used for moving the objects that are in front them which means that you must plan your moves. Our solution allows you to not only complete this puzzle but also to get Shadow Theater trophy (complete the puzzle in maximum number of ten moves).
Move 1) Use switch 12
Move 2) Use switch 5
Move 3) Use switch 1
Move 4) Use switch 6
Move 5) Use switch 3
Move 6) Use switch 8
Move 7) Use switch 6
Move 8) Use switch 11
Move 9) Use switch 8
The solution is presented in the picture above - shadows on both walls must completely overlap with the pictures. Completing this puzzle unlocks a passage in one of the chamber's corners and allows you to continue your journey.
Approach the new device and interact with it. This will activate a big lift. Sadly, your ride up has additional complications and you will be forced to escape from the elevator shaft before the central construction falls down. When you regain control over Chloe you must start climbing towards the upper left corner of the screen but you must also be ready to move to the opposite side of the giant hanging construction.
When you reach the top you must start running straight and perform a long jump. Start climbing on another monument. This will allow you to reach the top of the dam where you can meet with Nadine.
