Take a running jump to the metal box below and to the right. Keep running to the left and jump on the stacked boxes in the middle of the room, the pile with the wooden crate at the top. To make sure you land on the stacked boxes straightaway and not have to grab/ hoist, jump from the right hand corner of the metal box.

When you are there, stand next to the crate, having it on your right. When you see the shadow of the crane above you, tap back once and hang from the edge.

Immediately shimmy to the right and around the corner to another crate.

Pull up and then take a running jump to grab the stacked boxes ahead with the crate on the top.

Turn right to face the corner of the crate and take a standing jump to land on it. Keep running, and jump to grab the edge of the balcony. Then pull up (phew!).
