In Tomb Raider legend how do you get past the room full of water?

In Tomb Raider Legend, to get past the room full of water, you will need to use the grappling hook and the crank. Here are the steps:

1. First, locate the grappling hook point on the ceiling. It should be in the center of the room.

2. Use the grappling hook to swing over to the platform in the middle of the room.

3. Once you are on the platform, turn around and face the wall with the crank.

4. Use the crank to lower the water level in the room.

5. Once the water level is low enough, you can swim to the other side of the room and climb out of the water.

6. Continue through the water until you reach the next room.
