Marcellhs, veja se o que você procura está no trecho abaixo, tirado de um walkthrough em inglês, fase do Peru:
"RUINS
Run behind the boxes on the left and pick up the Bronze Reward (7/8). Go to the other side of the area (where the pool is) and search for a Bronze Reward (8/8) between the wooden supports. Jump into the water and swim down and through the tunnel. Follow it as it goes and keep and eye above to spot the surface. Take some air and dive back down. Follow the tunnel to the other side and swim between the broken bars. Again, you can find a spot where you can surface above. Continue through the tunnel until you reach a circular big underwater room. Here you can surface.
The water puzzle - Dive down and enter the passage, which is on the right as you entered this area. Get the Silver Reward (2/2) and return to get some air (or get it after solving the puzzle). You need to pull the four blue spheres, but they need be out together at the same time. Every time you pull one, it remains out for some seconds. You then need to swim around and pull the other three, so that all of them are out together. To avoid a possible drowning, try this: Surface above a sphere and dive down. Press the Interact button to pull it, then continue to the next sphere, pressing the Interact button whilst swimming to move faster. Keep pressing the Interact button to swim faster as you approach the sphere and Lara will grab it easier.
When you succeed, the cut scene shows Lara surfacing. A door opens and the room drains. Lara finds a shoe and assumes it belongs to Amanda. The shoe is unlaced, but she never imagined that Amanda could have survived.
There is an opening in one of the walls. Jump through it and approach the archaeological stone above."
