How to Get from Key to Key in the Stained Glass Heart Puzzle in Uncharted: Drake's Fortune

Press the "Select" button to bring out your journal. This triggers a scene showing you where you need to go to open the stained glass window.

Jump onto the wood ledge in front of you, then to the ledge on the right. Climb up the wall and jump to the ledge on the left.

Continue crossing ledges and moving left. When you reach a stone pillar, turn around and jump to it. Climb up.

Walk to the corner of the ledge. Jump onto the chandelier across from you. Wait for the chandelier to gain enough momentum, then jump off it onto the next ledge.

Jump from ledge to ledge, going right. Climb up the next pillar you see, and keep going right. Jump up when you see a ledge above you.

Follow the ledge as it leads you around the corner to the first key. Jump up and hang from the key. Drop down and head back to the chandelier.

Use the chandelier to swing to the other ledge on the right. Follow the ledge until you can climb on top of it. Walk around the corner. Jump up to grab the second key. This is the final key --- you're now able to enter the treasure room.

Move to the left on the key, then jump left. Continue moving this way until you see a chain on the left. Jump to it.

Hold on to the chain while running against the wall, then jump to the ledge on the left. Turn around and jump to the stained glass heart window. Enter the door that has opened to finish the puzzle.
